7. A 1.0 kg block is released from rest at point A as shown, a vertical distance, h, above the tabletop. It slides down an incline track, around a circular loop of radius 0.5 meter, then up another incline that forms an angle of 30° with the horizontal. The block slides of the track with a speed of 4 meters per second at point C which is a height of 0.5 meter above the ground. A (a) Assuming the track to be frictionless, set up an algebraic expression to solve for h. (b) determine h 0.5 m Ko B 30° 0.5 m (c) Another identical track but is NOT frictionless is used and it is found that if the block is to reach point C with a speed of 4 m/s, the height, h must be 2m. Determine the work done by the frictional force. 7. A 1.0 kg block is released from rest at point A as shown, a vertical distance, h, above the tabletop.
