Explanation / Answer

h = 36.1 m

As it reaches the ground,

vertical displacement, y = 0 - h = - 36.1 m

initial vertical velocity, v0y = 0 (because thrown horizontaly)

ay = -9.8 m/s^2


Applying y = v0y t + ay t^2 /2

- 36.1 = 0 - 9.8 t^2 /2

t = 2.71 sec


distance travelled by jogger = 2.90 x (9 + 2.71) = 34 m

in horizontal,

d = v0x t

34 = v (2.71)

v = 12.5 m/s ........Ans

(b) distance travelled by jogger = 34 m
