Arope pulls a 40 kg metal block 6 m up a ramp at constant velocity of 2 m/s. the ramp makes and angle of 18° with the horizontal. the tension on the rope running parallel to the ramp is 1500 n a) draw a free body diagram showing all the forces acting on the metal block (b) how much work is done by the force of tension pulling the log 6 m up the ramp? (c) how much work is done by gravity pulling the block 6 m up the ramp? (d) how much work is done by the normal force pulling the block 6 m up the ramp? (e) how much work is done by the friction force pulling the block 6 m up the ramp? (f) determine the coefficient of friction between the block and ramp (g) while the block is in rest at the top of the ramp, the rope breaks down and the block slides downwards along the incline. how fast is it moving as it reaches the bottom of the ramp?

The block moves up an incline with constant speed. what is the total work wtotal done on the block by all forces as the block moves a distance l = 3.60 m up the incline? include only the work done after the block has started moving at constant speed, not the work needed to start the block moving from rest.

A195 g block is pressed against a spring of force constant 1.60 kn/m until the block compresses the spring 10.0 cm. the spring rests at the bottom of a ramp inclined at 60.0° to the horizontal. using energy considerations, determine how far up the incline (in m) the block moves from its initial position before it stops under the following conditions(a) if the ramp exerts no friction force on the block(b) if the coefficient of kinetic friction is 0.440 tm(c)what if? if the ramp is 4.00 m long, what is the maximum coefficient of friction that would allow the block to reach the end of the ramp?
