A box slides down a frictionless 35 degree incline. Determine its acceleration. If the incline is 10.0 m long and the box starts from

rest, how much time does it take to get to the bottom?

1 answer

component of gravity force down slope = m g sin 35
so
a = g sin 35

10 = (1/2) a t^2
20 /(g sin 35) = t^2
