The same 2 kg ball is allowed to roll down two different ramps, one inclined at 15 degrees and the other at 70 degrees. the ball begins at rest at the top of each ramp.

in free body diagrams, draw the force vectors for each ramp and calculate, in newtons: a) the magnitude of the normal force, b) the magnitude of the downward force under the ball due to gravity (i. e., it’s weight) and, c) the magnitude of the net, resultant force accelerating the ball down the ramp.
