You push a block of mass 24kg up a frictionless ramp that makes an angle 0.4189rad as measured from horizontal. Immediately after the block leaves your hands it has a velocity of magnitude 11m/s. The block travels up the ramp, reaches its highest point, and heads back down the ramp.
When is the magnitude of the block's acceleration the greatest?
a) On its way up the ramp.
b) On its way down the ramp.
c) At its highest point.
d) The magnitude of the net force on the block is constant throughout its motion.
