A ball is thrown straight down from the edge of a cliff so that its speed starts at 30 m/s. Assuming that this ball has the free fall acceleration of 10 m/s/s down, what will be the speed of this ball 3 seconds after it is thrown?

Step 1
Step 1: Given initial velocity (u) = 30 m/s, acceleration (a) = 10 m/s^2, and time (t) = 3 seconds. Show more…

A ball is thrown down from 30m above the ground and lands 2 sec later. What is the balls final speed when it lands
Mahendra K.
A ball rolls off a cliff with a horizontal velocity of 10 m/s. It hits the ground with a velocity of 30 m/s. Determine the vertical component of its velocity at the moment it hits the ground and the height of the cliff.
Ravindra Y.
A ball is thrown vertically up with a velocity of $30 \mathrm{m} / \mathrm{s}$ at the edge of a $60-\mathrm{m}$ cliff. Calculate the height $h$ to which the ball rises and the total time $t$ after release for the ball to reach the bottom of the cliff. Neglect air resistance and take the downward acceleration to be $9.81 \mathrm{m} / \mathrm{s}^{2}$
