A ball of mass 10 g is moving with a velocity of `50 "ms"^(-1)`. On applying a constant force on ball for 2.0 s, it acquires a velocity of `70 "ms"^(-1)`. Calculate the initial momentum of ball

Explanation

To solve the problem, we need to calculate the initial momentum of the ball using the formula for momentum, which is given by:

\[ \text{Momentum} (p) = \text{mass} (m) \times \text{velocity} (v) \]
