a block is given an initial velocity of 3 m/s up the 22 degree plane.

A.) How far up will the plane go
B.) How much time elapses before it returns to its starting point. IGNORE FRICTION

A) I got 1.2m
B.) I got 1.6s

I'm confused on this question:
Both questions I think go together

Problem 53: repeat assumming Uk=0.20 between the block and plane?

1 answer

weight down the plane: mgSinTheta
acceleration gravity down the plane: g*cosTheta

at the top, vf=0
vf^2=vi^2+2ad solve for d, given a as above, -9.8cosTheta

df=di+vi*t+1/2 a t^2, same a, df=di=0, solve for t.
