Answer:
0.992 m
Explanation:
x = (horizontal vi)t + (1/2)at²
18 = (40)t + 0
t = 0.45 s
y = (vertical vi)t + (1/2)gt²
y = 0 + (1/2)(9.8)(0.45)²
y = 0.992 m

Answer:
The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules.
