A ball starts from rest at the left end of the track shown in the figure below. The ball flies off the right end of the track and follows the parabolic trajectory shown. Suppose the right end of the track is 1.6 m above the floor and makes an angle of 39.0° with the horizontal. Also suppose the ball leaves the track with a speed of 4.2 m/s. Determine where the ball hits the floor. m Ball starts from rest

The drawing shows two frictionless inclines that begin at ground level (h = 0 m) and slope upward at the same angle θ. One track is longer than the other, however. Identical blocks are projected up each track with the same initial speed v0. On the longer track the block slides upward until it reaches a maximum height H above the ground. On the shorter track the block slides upward, flies off the end of the track at a height...

A homogenous sphere of mass M = 1.61 kg and radius R = 12.82 cm starts from rest at the upper end of the track (height H = 1.13 m) shown in the Figure and rolls without slipping until it rolls off the right-hand end (height h = 0.74 m). The track is horizontal at the right-hand end. What is the distance to the right of point A at which the ball strikes the horizontal base line?

Assume that you can neglect friction on this icy track, and the rider lies on the luge in such a way as to minimize air resistance, so you can neglect that, too. The track hasta circular loop with radius R...

Problem 20 A golfer hits a shot to a green that is elevated 3.10 m above the point where the ball is struck. The ball leaves the club at a speed of 18.6 m/s at an angle of 35.0˚ above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands.
