a 1000 kg car accelerates from 0 to 15 m/s in 5.0 s with negligible friction and air resistance. what is the average power delivered by the engine

30.16 hp

Explanation:

Given :

m= 1000 kg

v=15 m/s

t=5.0 s

The average power delivered by the engine can be determined by using the given formula

where m=,mass, v=velocity and t=time

Now putting the value of m,v and t in the previous equation we get

To convert w to hp we divide by 746

Therefore 30.16 hp is the answer.

i think they are all correct

explanation:

they seem good
