Let's assume that the car, of mass 1550 kg, can reach a speed of 26.8 m/s in 7.1 s. What is the average power needed to accomplish this? (Given : 1 hp = 746 Watt)

A

105 hp

B

110 hp

C

1210 hp

D

1040 hp

Text Solution

Verified by Experts

The correct Answer is:
A
`P_(av) =(W_("Total"))/("time")=((1)/(2)mv^(2))/("time")=((1)/(2)(500)(26.8)^(2))/(7.1) //746`
