Explanation / Answer

Consider the motion along Y-direction

Y = vertical displacement = - 2 m

Voy = initial velocity in Y-direction = 18 Sin30 = 9 m/s

ay = acceleration in Y-direction = - 9.8 m/s2

t = time taken

Using the equation

Y = Voy t + (0.5) ay t2

- 2 = 9 t + (0.5) (-9.8) t2

t = 2.04 sec

Along the X-direction

Y = Horizontal displacement

Vox = initial velocity in X-direction = 18 Cos30

ax = acceleration in X-direction = 0 m/s2

t = time taken = 2.04

Using the equation

X = Vox t + (0.5) ax t2

X = (18 Cos30 ) (2.04)

X = 31.7 m
