We know that S=ut+.5gt*t here s=84m g=9.8m/s*s u=0 hence time is 4.14secs.

Due to a golf ball being so hard it hits the ground the energy is so strong it bounces up higher than any other ball. A golf ball is so hard and that energy just can't wait to get released and bounces up very high. There is many layers in a golf ball. All the layers are Sort of like rubber material so then that is why a golf ball bounces the highest.
About 40 to 44 inches.

They should reach the ground together, since their initial vertical speed is the same, namely zero.
As , s = ut + 1/2 a t2 , since a ball is dropped , the equation is modified as h = ut + 1/2 g t2 Therefore , h = 0 x t + 1/2 x 9.8 x 22 [ u = 0 ,since the ball is at rest] h = 19.6 meters Height of the window = 19.6 meters

64 metersIf a ball is thrown horizontally at 20 m/s from the top of a cliff that is 50 meters high, the ball will strike the ground 64 m from the base of the cliff (20m/s x 3.2 s).
We know that S=ut+.5gt*t here s=84m g=9.8m/s*s u=0 hence time is 4.14secs.
Answer: 44 meters
i think it will be 35inches
"3.2" or "3.20" please put all of that
