A ramp of length 5m is inclined 30 degrees to the horizontal. A parcel of mass 1kg, which may be modified as a particle is placed at rest on top of the ramp and allowed to slide down. The speed of the parcel at bottom is 7ms-1. Is this data consistant with the ramp being smooth and their being no air resitance. Explain why.
Help please?? So confused
if the incline is frictionless, then the acceleration of the mass down the incline is, where
is the angle of the incline w/r to the horizontal.
you were given a displacement (5 m), an initial velocity (0), and a final velocity (7 m/s) ... use your knowledge of kinematics to determine the actual acceleration of the mass, then compare it with the value of.
