Answer:
171.5Watts
Explanation:
Given parameters:
Mass = 5kg
Distance = 28m
Time = 8s
Unknown:
Power = ?
Solution:
Power is the rate at which work is done;
Power =
Work done = force x distance = mg x d =
m is the mass
g is the acceleration due to gravity
d is the distance
Work done = 5 x 9.8 x 28 = 1372J
Power =
= 171.5Watts
Answer:
<h2>A. ma</h2>
Explanation:
Force = mass × acceleration
F = ma
