Question

A ball, moving at 30 m/s towards south, is hit by a cricketer by his bat. As a result, the ball moves towards
north at 20 m/s. What is the change in velocity? If the collision lasts for 0.02 s, what is the acceleration?​

please please answer it​

Answer 1

Answer:

Explanation:

change in velocity if we consider north as y axis and east as x axis

change in velocity = final - initial = 20i+30i = 50i

take magnitude which is 50

acceleration = 50/0.02 = 2500 m/sec^2
