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?

Answer 1

Answer:

Solution -

1.

\longrightarrow⟶ m = 0.01 kg

\longrightarrow⟶ u = 50 m/s

\boxed{p_1 = mu}

p

1

=mu

\longrightarrow⟶ p_1p

1

= 0.01 × 50

Initial momentum = 0.5 kg m/s
