Answer:
When he weight of the car is 8.55 x N then power = 314.012 KW
When he weight of the car is 1.10 x N then power = 43.76 KW
Explanation:
Given that
Initial velocity = 0
Final velocity = 24.8
Time = 7.88 sec
We know that power required to accelerate the car is given by
P =
Change in kinetic energy Δ K.E =
Since Initial velocity = 0
⇒ Δ K.E =
⇒ Power P =
⇒ Power P = -------- (1)
(a). The weight of the car is 8.55 x N = 8550 N
Put all the values in above formula
So power P =
P = 314.012 KW
(b). The weight of the car is 1.10 x N = 11000 N
Put all the values in equation (1) we get
P =
P = 43.76 KW
