The engine of a toy car provides a force forwards of 8 N while the car is moving. If the car moves at an average velocity of 3.4 m/s while the engine is on, what is the power of the engine?
Question
The engine of a toy car provides a force forwards of 8 N while the car is moving. If the car moves at an average velocity of 3.4 m/s while the engine is on, what is the power of the engine?
Solution
To solve this problem, we need to use the formula for power which is:
Power = Force x Velocity
Given in the problem, we have:
Force = 8 N Velocity = 3.4 m/s
Substitute these values into the formula:
Power = 8 N x 3.4 m/s = 27.2 Watts
So, the power of the engine is 27.2 Watts.
