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.

the pull of gravity on the rocket decreases

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
