An object of mass 5 kg is initially moving with a velocity of 10 m/s. ...
Given:
Mass of the object (m) = 5 kg
Initial velocity (u) = 10 m/s
Force applied (F) = 30 N
To find:
Acceleration of the object (a)
Explanation:
Newton's second law of motion:
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed as:
F = ma
Calculating the acceleration:
To find the acceleration of the object, we can rearrange the formula as:
a = F/m
Substituting the given values:
a = 30 N / 5 kg
a = 6 m/s^2
Therefore, the acceleration of the object is 6 m/s^2.
Answer:
The correct answer is option A) 6 m/s^2.
An object of mass 5 kg is initially moving with a velocity of 10 m/s. ...
To calculate the acceleration of the object, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration.
Given:
Mass of the object (m) = 5 kg
Initial velocity (u) = 10 m/s
Force applied (F) = -30 N (opposite direction of motion)
Using Newton's second law, F = ma,
we can rearrange the equation to solve for acceleration (a).
-30 N = 5 kg * a
a = -6 m/s2 (negative sign indicates the opposite direction)
Therefore, the acceleration of the object is 6 m/s2 in the opposite direction of its initial motion.
The correct answer is a) 6 m/s2.
