Final answer:
The power exerted by the weight lifter who lifts 875 newtons a distance of 2 meters in one second is 1750 Watts, which indicates the rate of work done.
Step-by-step explanation:
The power of the weight lifter can be calculated using the formula for power, which is the work done divided by the time taken. The work done by the weight lifter, in this case, can be found by multiplying the force applied (which is equivalent to the weight lifted, given by the force of gravity on the mass) with the distance the weight is lifted.
The formula for power (P) is given by:
P = Work done / Time taken = Force × Distance / Time
Here, the force exerted by the weight lifter is 875 Newtons, the distance moved is 2 meters, and the time taken is one second.
So, the power is:
P = 875 N × 2 m / 1 s = 1750 Watts (or Joules per second)
This value represents the rate at which the weight lifter is doing work to lift the weight.
