One horsepower is a unit of power equal to 746 W. How much energy can a 150-horsepower engine transform in 10.0 s?

Explanation:

Given:

time (t = 10.0 sec)

power = 150 Hp

We need to find the energy transformed by a 150 Hp engine in 10 s.

Solution:

First we convert 150 Hp in watt.

So, power (p = 111900 watt)

We know that, if we multiply power by time, we get energy transform by engine.

 -----------(1)

Where:

P ⇒ power.

E ⇒ Energy.

t ⇒ time.

Substitute p = 111900 watt and t = 10 s in equation 1.

Therefore, a 150 Hp engine could transform 1,119,000 joules energy  in 10 s.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

so easy. just google the electromagnetic waves and it’ll pop up.
