Question

A weightlifter lifts barbells from time t = 0 to t = 60 s. The amount of power that the weightlifter uses at t = 47.6 seconds is described as _____.

average power
work power
raw power
instantaneous power

Answer 1

do you know the average power used from time t = 0 to t = 60 s? If you do, is it the same as the power at t = 47.6 seconds? If you do not, how could you assess whether the average is the same as the power at that instant? Does average power seem like a good answer choice?

Do work power and raw power have definitions in your physics text?

If the amount of power used varies with time, what would be a good term to describe the power used at a specific time?
