Question

You do a physics lab experiment on another planet. A small block is released from rest at the top of a long frictionless ramp that is inclined at an angle of 36.9° above the horizontal. You measure that a small block travels a distance 17.0 m down the incline in 8.60 s. What is the value of g, the acceleration due to gravity on this planet?

Answer 1

ma = m g sin 36.9
so
a = g sin 36.9

d = (1/2) a t^2

17 = .5 (g sin 36.9) (8.6)^2
solve for g
