A., 101.7 km/h is the correct answer for this question
Answer: it is located over Ellesmere Island, Canada
Explanation
it is now drifting away from North America and toward Siberia.
Answer:
The power expended by the car during the acceleration is 116.38KW
Explanation:
Power is a term that defines the rate at which energy is expended whenever work is done.
Power can be given as Force X velocity.
Force can be found using the formula:
F = mass X acceleration.
In this case,
F = 1100kg X 4.6m/s2
F = 5060 N
The final velocity, v of the car can be obtained from this formula:
v = u+ at
U = initial velocity = 0 (since the car started from rest)
a = acceleration = 4.6m/s2
t = time = 5 seconds
v = 0 + 4.6 X 5 = 23 m/s
Therefore, the power expended is 5060N X 23m/s=116,380W
The power expended by the car during the acceleration is 116.38KW
