Question

A ball is thrown with some velocity u m/s. Show that under the free fall, it will fall on the ground with same velocity

*Urgent*​

Answer 1

Answer:

Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s
