Calculate the height of a cliff if it takes 2.25 s for a rock to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.01 m/s. (b) How long would it take to reach the ground if it is thrown straight down with the same speed?
A juggler throws a bowling pin straight up with an initial speed of 6.1 m/s from an initial height of 2.8 m. How much time elapses until the bowling pin returns to the same initial height?
Answer without rounding off
An object is thrown vertically up at an initial velocity of $3 m/s. At the maximum height, the final velocity of the object is
