Question
The power of the chain motor on a roller coaster lift hill is 2 kW.It takes 60 seconds for the chain to take a train to the top of the lift hill.Calculate the work done when the train reaches the top of the lift hill.Work done = _____
Solution 1
The work done can be calculated using the formula:
Work Done = Power x Time
Given that the power of the chain motor is 2 kW (or 2000 Watts) and the time taken is 60 seconds, we can substitute these values into the formula:
Work Done = 2000 Watts x 60 seconds = 120,000 Joules
So, the work done when the train reaches the top of the lift hill is 120,000 Joules.
Solution 2
The work done by the chain motor can be calculated using the formula:
Work Done = Power x Time
Given that the power of the chain motor is 2 kW (or 2000 Watts) and the time taken is 60 seconds, we can substitute these values into the formula:
Work Done = 2000 Watts x 60 seconds = 120,000 Joules
So, the work done when the train reaches the top of the lift hill is 120,000 Joules.
Solution 3
The work done can be calculated using the formula:
Work Done = Power x Time
Given that the power of the chain motor is 2 kW (or 2000 Watts) and the time taken is 60 seconds, we can substitute these values into the formula:
Work Done = 2000 Watts x 60 seconds = 120,000 Joules
So, the work done when the train reaches the top of the lift hill is 120,000 Joules.
