A ball is launched horizontally from a cliff at 15 m/s. A second ball is dropped from rest from the same height at the same instant. Which of the following correctly compares the time each ball takes to reach the ground?

Accepted Answer

Both balls hit the ground at the same time because the vertical motion is independent of horizontal motion.

Accepted Answer

Zero, because the normal force is perpendicular to the displacement of the box

Answer

Positive, because the normal force supports the box against gravity

Answer

Negative, because the normal force acts opposite to the direction of motion

Answer

Zero, because the box moves at constant velocity and no net work is done by any force

Question 7

Accepted Answer

The KE at the bottom equals the initial gravitational PE minus the thermal energy produced by friction

Answer

All gravitational PE converts to KE because the block is in motion throughout

Answer

Friction increases the total mechanical energy of the block-ramp system

Answer

The KE at the bottom equals the initial gravitational PE because total energy is always conserved

Kinetic energy increased by more than the gravitational PE decreased

Answer

The system is frictionless because kinetic energy is present at the end of the motion

Answer

4 m/s to the right, because the total mass doubles so velocity is unchanged

Answer

1 m/s to the right, because kinetic energy is conserved in all collisions

Answer

2 m/s to the right, because the combined mass is the average of both individual masses

Question 13

A force-time graph shows a rectangular pulse: a constant force of 8 N acts from t = 1 s to t = 4 s, and the force is zero outside this interval. What is the impulse delivered to the object during this time interval?

Accepted Answer

24 N·s, because impulse equals the area under the force-time graph

Answer

8 N·s, because impulse equals the peak force value on the graph

Answer

32 N·s, because impulse equals force times the total elapsed time from t = 0

Answer

2 N·s, because impulse equals force divided by the duration of the pulse

Question 14

Accepted Answer

3 m/s to the right, because total initial momentum is zero and must remain zero

Answer

2 m/s to the left, because both astronauts experience equal and opposite forces

Answer

1.5 m/s to the right, because the lighter astronaut moves slower

Answer

3 m/s to the left, because the lighter astronaut moves in the same direction as the heavier one

Question 15

A 40 N force is applied at the end of a 0.5 m wrench handle at an angle of 30° measured from the direction of the handle. What is the magnitude of the torque produced about the pivot point at the other end of the wrench?

Accepted Answer

6 rad/s, because angular momentum is conserved when no external torque acts

Answer

2 rad/s, because angular velocity cannot change without an external torque

Answer

0.67 rad/s, because angular velocity decreases proportionally as moment of inertia decreases

Answer

4 rad/s, because rotational kinetic energy is conserved during the arm pull

Accepted Answer

T₂ = T₁, because the period of a pendulum is independent of its mass

Answer

T₂ = 3T₁, because the period scales directly with the mass of the pendulum

Answer

T₂ = √3 × T₁, because the period depends on the square root of the mass

Answer

T₂ < T₁, because the heavier bob experiences a greater gravitational restoring force

Question 24

Question 27

Container X is a wide cylinder and Container Y is a narrow cylinder. Both are filled with the same fluid to the same height h. Which of the following correctly compares the pressure at the bottom of each container?

Accepted Answer

The pressures are equal, because fluid pressure at a given depth depends only on fluid density and depth

Answer

Container X has greater pressure, because it holds a greater total volume of fluid

Answer

Container Y has greater pressure, because the fluid is confined to a smaller cross-sectional area

Answer

Container X has greater pressure, because the larger base area results in a greater total downward force

Question 28

A wooden block with a mass of 0.5 kg and a volume of 8 × 10⁻⁴ m³ is fully submerged in water (ρ_water = 1000 kg/m³, g = 9.8 m/s²). What is the magnitude and direction of the net force on the block?

Accepted Answer

2.94 N upward, because the buoyant force exceeds the gravitational force

Answer

4.9 N upward, equal to the weight of the block

Answer

7.84 N upward, equal to the buoyant force alone

Answer

0 N, because a wooden block always reaches equilibrium when fully submerged

Question 29

Question 30

According to Bernoulli's principle, as an ideal fluid flows through a constricted (narrower) section of a horizontal pipe where the fluid velocity increases, what happens to the fluid pressure in that section?

Accepted Answer

Pressure decreases, because the increase in kinetic energy per unit volume corresponds to a decrease in pressure energy

Answer

Pressure increases, because more fluid molecules collide with the pipe walls per unit time

Answer

Pressure remains constant, because the same fluid flows throughout the entire pipe

Answer

Pressure increases, because the narrower section provides less space for the fluid to occupy
