Question

Max is taking his human, Frank, for a walk. Answer the three questions below using three significant figures. Part A: You can see that Frank is getting dragged behind Max, and this means that Max has to pull with a force of 290 N. How much power ( P 1 ) does Max have to supply in order to pull Frank at a speed of 0.425 m/s?

Answer 1

The power that Max has to supply is 123.25 W

Step-by-step explanation:

Given data:

F = 290 N

v = 0.425 m/s

The power that Max has to supply is:

P = F * v = 290 * 0.425 = 123.25 W

Answer 2

123.25 W

Step-by-step explanation:

Part A

Power: The can be defined as the rate at which energy is used up. The S.I unit of power is Watt(W).

From the question,

P1 = F×v..................... Equation 1

Where P1 = Max's power, F = Force used by max to pull Frank, v = velocity of Frank.

Given: F = 290 N, v = 0.425 m/s

Substitute into equation 1

P1 = 290×0.425

P1 = 123.25 W.

Hence the power supplied by Max = 123.25 W
