An object begins at rest on a frictionless inclined plane at a linear distance of 2.0m from the base of the incline. If the incline makes an angle of 20 degrees with the horizontal, determine the time it will take for the object to reach the base of the incline.

Answer 1

the acceleration down the plane is 9.8m/s^2 * sinTheta

distance=1/2 acceleration*time^2
solve for time, given acceleration above, and distance in the problem.
