Maurice is playing some of the arcades at the county fair. At one booth he throws a 1.2-kg ball forward with a velocity of 15 m/
s and hits a 0.5-kg can
at rest. The ball continues forward at 9 m/s. What is the new velocity of the can, in m/s? (Round your answer to one decimal place if necessary.)

Explanation:
Power is defined as the rate at which work is done in per unit time.
Mathematically,
It is given that work done by engine is 4,560,000 J and time is 20 minutes.
There is 60 seconds in 1 minute. So, convert minutes into seconds as follows.
= 1200 seconds
Calculate power output of the engine as follows.
=
= 3800 J/s
or, = 3800 Watt
Therefore, the power output of the engine is 3800 Watt.
