Question:

A tow truck is hired to pull out a 2000 Kg Car from a 10 meter deep ditch straight up and place it on the level ground. If the work is completed by the truck in 5 seconds Calculate horse power of the truck.
Round your answer
A) 530.0 hp
B) 53.0 hp
C) 5.30 hp
D) 0.53 hp

Answers

Answer:B) 53.0 hpExplanation:If you want to calculate horsepower, you need to calculate the work first. The work formula is Force x Distance. The force is Mass x Acceleration, and since this is most likely happening on Earth, the acceleration due to gravity is 9.8 m/s/s. So, multiply 2000 x 9.8 would give you the force. (19600) So, taking the force and multiplying it by the distance would give you the work of 196,000. The next step for calculating the horsepower is power. Power is work/time. So, taking the work from the previous step of 196000 and divide it by 5 would give you 39200.  That would be 39200 Watts of power, and 1 horsepower is 745 Watts, dividing 39200 by 745 would get the answer of 52.617 horsepower or roughly 53 horsepower.
