Okay thank you!

I really have no clue how to start this. I think I might have to use Pythagoras but I'm really not sure.

Homework Statement A 5.21 kg block is sliding down a slope at an angle of 4.22° to the horizontal. The block is initially moving down the slope at a speed of 1.45 m s−1 and the coefficients of friction between the block and slope are, μs = 0.500, and μk = 0.100. Find an expression for the...

Okay thank you for your response!

So here's the problem: A sled slides down a long snow-covered slope that is at an angle θ to the horizontal. Kinetic friction acts on the sled as it slides where the kinetic coefficient of friction between the sled and snow is μk = 0.050. Ignore air-resistance when solving this problem. If we...
