Final answer:
The power required to perform 120 joules of work in 2 seconds while riding a toboggan is 60 watts.
Step-by-step explanation:
When riding a toboggan down an icy run to a frozen lake and performing 120 joules of work in 2 seconds, we need to calculate the power required for this activity. Power is defined as the rate at which work is done or energy is transferred. It is given by the formula:
Power = Work / Time
In this scenario, the work done is 120 joules and the time taken is 2 seconds. Therefore, the power can be calculated as follows:
Power = 120 joules / 2 seconds = 60 watts
So the power required to perform 120 joules of work in 2 seconds is 60 watts.
