A ball is thrown horizontally off the edge of a cliff with an initial speed of 20.0 m/s. How long would it take for the ball to reach the ground 15.4 m below if it were dropped from rest off the cliff edge?
Added by Kristin K.
Step 1
First, let's consider the ball being dropped from rest off the cliff edge. In this case, the only force acting on the ball is gravity, which causes it to accelerate downwards at a rate of 9.8 m/s^2. Show more…

A ball is thrown horizontally off the edge of a cliff with an initial speed of $20.0 \mathrm{m} / \mathrm{s} .$ (a) How long does it take for the ball to fall to the ground 20.0 m below? (b) How long would it take for the ball to reach the ground if it were dropped from rest off the cliff edge? (c) How long would it take the ball to fall to the ground if it were thrown at an initial velocity of $20.0 \mathrm{m} / \mathrm{s}$ but $18^{\circ}$ below the horizontal?
A person stands on the edge of a straight 20m-high cliff and holds a ball over the edge. The person tosses the ball directly upward with an initial speed of 5ms. How long will it take the ball to hit the ground at the base of the cliff, 20m below?

(a) Calculate the height of a cliff if it takes 2.35 s for a rock to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.00 m/s. (b) How long would it take to reach the ground if it is thrown straight down with the same speed?
