Question
An object released from rest slides down a frictionless ramp
that makes an angle 0j of 60.0° with the horizontal. The
object begins at a height Hj of 12.0 m above the base of the
ramp. The bottom end of the ramp merges smoothly with a
H
second frictionless ramp that rises at angle 02 of 39.0°.
H2
What distance d does the object slide along the second
ramp before coming to a momentary stop?
d =
m
When the object is on its way back down the second ramp,
what is its speed vr at the moment that it is at a height H2
of 7.00 m above the base of the ramp?
Uf =
m/s
