Beginning from rest, an object of mass 200 kg slides down a 9-m-long ramp. The ramp is inclined at an angle of 20o from the horizontal. Air resistance and friction between the object and the ramp are negligible. Let g = 9.81 m/s2.

Determine the kinetic energy of the object, in kJ, and the velocity of the object, in m/s, at the bottom of the ramp.

10 kg point mass located at the top of a 1.50 m inclined ramp that is without friction. The ramp makes a 30 degree angle with the horizontal. The bottom half of the ramp is on a table and is 0.66 m above the ground. When mass is released from rest, it slides down the ramp ( a=4.9 m/s2 ) & off the table, then goes through the air until it hits the ground. (table & ramp don't move) The...
