Explanation / Answer

a)

consider the motion in vertical direction

Voy = initial velocity = 0 m/s

t = time of travel

Y = vertical displacement = - 1.63 m

a = acceleration = - 9.8

using the equation

Y = Voy t + (0.5) a t2

- 1.63 = 0 t + (0.5) (-9.8) t2

t = 0.58 sec

b)

Vox = horizontal velocity = 1250 m/s

t = time = 0.58 sec

horizontal distance travelled is given as

X = Vox t = 1250 x 0.58 = 725 m
