M1 question

Question attached

Coeff friction is 0.082
velocity at bottom of hill is 8m/s

how do I find acceleration down the hill?
I assume you find F from coefficient of friction x R but not entirely sure how to form the equation nor do I understand the angle given :colondollar:

any help appreciated, thank you!

Possibly you have neglected to use a component of the weight to form the force equation. If you know the force you know a and if you know v and the fact that u =0 you can find s

The force of the toboggan down the hill is mgsin#, where g is the gravitational acceleration, and the force of friction is Xmgcos#, where # is the angle, m is the mass of the toboggan and X is the coefficient of friction, I hope you can work it out from here. :smile:
