How do you find the speed of a ball when it hits the ground?
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.
Are cricket ball is dropped from a height of 20m?
Thus the ball takes 2 second to fall through a height of 20 metres .
Which of the following decreases when the ball is dropped?
kinetic energy
Its potential energy increases and kinetic energy decreases during the falls.
What is ascent formula?
Zigya App. Derive the ascent formula. Let a capillary tube of uniform bore be dipped vertically in a wet liquid. Since liquid is wet, therefore, the meniscus is concave. Let r be the radius of capillary tube, R be the radius of meniscus and θ the angle of contact.

What is the final velocity of a ball dropped from 20m?
The ball will have a final velocity of 49.96 meters per second downwards.* *Actually the final velocity should be 50 m/s downwards . The above calculation includes rounding errors. A ball is dropped from a height of 20m.
Does the thrown object reach the ground before the dropped object?
Generally the thrown object will have a vertical component to it’s initial velocity and if it is downward (upward) it will reach the ground before (after) the dropped object. This is seen from the velocity (thrown case): where v (0) is the vertical component of initial velocity.
