Answer:
x = 2.044 m
Explanation:
given data
initial vertical component of velocity = Vy = 2sin18
initial horizontal component of velocity = Vx = 2cos18
distance from the ground yo = 5m
ground distance y = 0
from equation of motion


solving for t
t = 1.075 sec
for horizontal motion

x = 2cos18*1.075
x = 2.044 m
