A 3.00kg crate slides down a ramp. The ramp 1.00m in length and the incline plane is at a 30° angle. The crate starts from rest at the top, experiences constant frictional force of magnitude 5.00N, and continues to move a short distance on the horizontal floor after it leaves the ramp.
A) Find the final speed of the crate?
uesnewton second law to find the acceleration of the crate along the ramp and ues the equation of kine meatics to determine the final speed of the crate?
sol
3.23m/s^2 : 2.54m/s
assuming the ramp to be frictionless find the final speed of the crate and its acceleration along the ramp
sol
3.13m/s : 4.99 m/s^2
