If two bodies of different masses, initially at rest, are acted upon by the same force for the same time, then the both bodies acquire the same:
A. Velocity
B. Momentum
C. Acceleration
D. Kinetic energy
Answer: Option B
Solution(By Examveda Team)
Since the Force and the duration of time for which it acted are same, the product of force and time will be the same for both. Since Force×time gives change in momentum of a body, and they had 0 momentum initially, their final momenta will be same.This Question Belongs to General Knowledge >> Physics

It is easier to roll a stone up a sloping road than to lift it vertical upwards because

Momentum will be different as there are mass different
Momentum will be different. Velocities will be the answer.
Impluse is right
Yes momentum is the answer bcoz force and time are equal in both cases. Sooo force *time =momentum.
Force and time same then momentum also same
Here 2 bodies have different masses , for a same force applied on both bodies then momentum will be different.. Here same force on same time is mentioned.. Hence acceleration will be same bcz its independent of mass of a body.. So c may be the answer
Momentum is the product of velocity and mass. Velocity is a vector quantity. The information given does not dictate a direction hence there is no way to determine velocity and thus momentum. Acceleration is also a vector quantity. So the only logical answer is D.
Momentum is the product of mass and velocity. Hence when velocity is more then mass is less and vice-varsa. At large momentum, large force requires to stop it.
why momentum not velocity or kinetic energy
