Question
A block of mass 2.00 kg starts from rest at the edge of the ramp as shown. It is pushed up
the ramp by a 30.0 N force, F, acting parallel to the ramp as shown. The ramp makes an
angle of 40.0° with the horizontal. Assume the ramp is smooth. When the block reaches the
top of the ramp, the force F stops acting so that the block is only under the influence of
gravity. It takes the block t=5 seconds to reach point A. The block is therefore launched
from the top of the ramp and follows a parabolic trajectory in the air. Take the acceleration
due to Earth's gravity to be 9.81 m/s².
40-
How much time (measured starting at point A) does it take for the block to travel from the
edge of the ramp (point A) to the top of its trajectory (point B)? Clearly show all work and
steps.
