Question
A ball starts from rest and accelerates at 0.5 m/s² while moving down on a 9 m long inclined plane.
10)
When the ball reaches the bottom of this plane, it continues moving with constant velocity along 12 m long horizontal
path. Then, it moves up the second inclined surface for 10s and it stops.
a) What is the speed of the ball at the bottom of the first inclined plane?
b) How long does it take for the ball to reach the bottom of the second
inclined plane?
c) What is the acceleration in the second inclined plane?
d) What is the speed of the ball at the point 8 m away from the bottom of
the second inclined plane?
Answers: a) v = 3 m/s, b) t = 10 s, c) a = -0.3 m/s² (parallel to that surface and in the downward direction), d) v =2.05
