Finding Power: Wayne exerts a force of 66.2 N to pull a sled

Wayne exerts a force of 66.2 N to pull a 313 N sled along a snowy path using a rope that makes a 28◦ angle with the ground. The sled moves 38.1 m in 2.2 s.

What is Wayne’s power? Answer in units of W


If someone could possibly work this out step-by-step for me to follow that would be great. It's an exam review and this is the only one I have left before Tuesday's exam!

Thanks

By W = F.s
=>W = F x s x cosθ
=>W = 66.2 x 38.1 x cos28*
=>W = 2226.99 J
=>By P = W/t
=>P = 2226.99/2.2
=>P = 1012.27 Watt
=>P ≈ 1 kW
