Aball is projected horizontally from the top of a 92.0-meter high cliff with an initial speed of 19.8 m/s. determine: (a) the horizontal displacement and (b) the final speed the instant prior to hitting the ground.

Part a)

Part b)

Explanation:

Part a)

As we know that ball is projected horizontally

so here the vertical speed of the ball is zero

now we have

now we have

now in the same time the horizontal distance covered by the ball

Part b)

now the horizontal speed of the ball always remains constant

so we have

now in vertical direction we have

so the final speed of the ball is given as

1= 26.17

2= 1.17

3=30.86

4=5.86
