Solution

To solve this problem, we need to find the work done and then use the formula for power.

Step 1: Calculate the work done Work done is given by the formula: Work = Force x Distance x cos(θ) Where: Force = 42.1 N Distance = 16 m θ = 45.0°

So, Work = 42.1 N x 16 m x cos(45.0°)

Step 2: Calculate the power Power is given by the formula: Power = Work / Time Where: Work = result from step 1 Time = 3.0 s

So, Power = Work / 3.0 s

Now, you just need to plug in the numbers and calculate.
