A small block with mass 0.308 kg is sliding down a frictionless ramp that is inclined at an angle of 53.1° above the horizontal. Assume
g = 9.80 m/s2.
(a) As the object slides down the incline, what is the magnitude of the normal force that the surface of the incline exerts on the block?
(b) As the object slides down the incline, what is the magnitude of the component of the gravity force parallel to the surface of the incline?
