A body starts to slide over a horizontal surface with an initial velocity of 0.2 m/s. Due to friction, its velocity decreases at the rate of 0.02 m/s2. How much time will it take for the body to stop?

Detailed Solution for MCQ: Equations of Motion - Question 3
Initial velocity, u = 0.2 m/s. 
Final velocity, v = 0 
Acceleration, a = 0.02 m/s^2.
v = u + at 
0 = 0.2 - 0.02 x t
0.02 x t = 0.2 
t = 0.2/0.02 = 10 sec.
Thus, the body will take 10 seconds to stop.

If you whirl a stone on the end of the string and the string suddenly breaks, the stone will:
Detailed Solution for MCQ: Equations of Motion - Question 4
The correct option is A because when a stone is whirling around ,tied to a string its direction of the motion is constantly changing ,even if the speed/velocity is uniform.At the time of the string breaking,the stone because of it inertia of motion follows the direction which it had at the time of string breaking,which is mostly the tangent.

To describe the motion of an object we first specify a
Detailed Solution for MCQ: Equations of Motion - Question 5
Yes this is because we need to observe the motion of object or rest of object from any point called reference point.

The third equation of motion is
Detailed Solution for MCQ: Equations of Motion - Question 6

The third equation of motion is :- 
 ( v² - u² = 2as) 
Here,
u = initial velocity 
v =  final velocity 
a =  acceleration
s =  distance

MCQ: Equations of Motion - Question 8
Save

The equations of motion can be derived by using:
Detailed Solution for MCQ: Equations of Motion - Question 8

Consider a velocity - time graph for a uniformly accelerated body starting from rest is represented as follows.

u = velocity at time t1 
v =  velocity at time t2 
If acceleration is represented as a, then, acceleration is defined as the rate of change in velocity. 
⇒  a = v-u / t2 - t1 
⇒ a = v-u /t 
Or,v-u = at 
⇒ v= u + at

A racing car has a uniform acceleration of 6 m/s2. In 10s it will cover:​
Detailed Solution for MCQ: Equations of Motion - Question 9

Given:Acceleration = 6 m/s^2Time = 10 secAs car start from rest so intial velocity will be zero.u = 0S = ut + 1/2(at^2)S = 0 + 1/2 x 6 x 100S = 300 m.

MCQ: Equations of Motion - Question 10

A body performs an accelerated motion, with uniform speed. The motion of body is
Detailed Solution for MCQ: Equations of Motion - Question 10
This is because in circular motion body is continuously changing its speed and acceleration is the change of velocity.
