Question

A ball of mass 0.01 kg is moving with a velocity of 50 m/s. On applying a

constant force for 2 seconds on the ball, it acquires a velocity of 70 m/s.

●Calculate the initial and final momentum of the ball.

●Also, calculate the rate of change of momentum and the acceleration of the

ball.

●What would be the magnitude of the force applied?​i​​

Answer 1

Explanation:

Initial momentum is 0.5 kg m/s . Final momentum is 0.7 kg m/s . Rate change of momentum 0.1 kg m/s² .

Answer 2

Answer:

mass =10g=100010=10−2kg

Initial velocity, u=50ms−1

Initial momentum = mass × Initial velocity

=10−2×50

=0⋅5kgms−1
