I need help with this Hw Problem.
The box below has been given an initial velocity of 2.60 m/s directed up the ramp. The angle the incline makes with the horizontal is 34.0°. The coefficient of static friction between the box and the
ramp is 0.430 while the coefficient of kinetic friction between the box and the ramp is 0.280. Use g = 9.80 m/s2.
(a) Calculate the magnitude of the box's acceleration while it is sliding up the ramp.
m/s2
(b) How far (measured parallel to the incline) does the box travel before coming instantaneously to rest?
m
(c) After the box comes instantaneously to rest on the ramp, it then either starts sliding down, or remains at rest. Either enter 0, if you determine that the box remains at rest, or calculate the
magnitude of the box's acceleration while it is sliding back down the ramp.
