Question

a small rock is projected vertically upwards with a speed of 10.0 M/s from the side of a bridge at a point 65.0 M above the water below. g=9.8 m/s2.

a) how much later (t final) will the stone strike the water surface?

b) find the velocity (V final) of the rock just before it hits the water.

c) how high (h) will it rise above the bridge?

d) how long does it take (t peak, time at peak) for the stone to rise to the peak of it flight ?

e) what is the magnitude and direction of the stone's velocity (V Peak) and acceleration (a p) at the instant when it is atthe peak of it's flight ?
