A daredevil on a motorcycle leaves the end of a ramp with a speed of 29.0 m/s as in the figure below. If his speed is 27.3 m/s when he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance.
A 145 kg crate slides down a ramp, starting from rest. The ramp is inclined at an angle of 20.6 degrees with respect to the horizontal and has a height of 1.74 m. The crate is placed on frictionless casters so that it slides down the ramp without friction. What is the final speed of the crate (in m/s) just as it reaches the bottom of the ramp? Use g = 9.81 m/s?.
A 51.2 kg sled coasts down a hill, starting from rest. The hill is inclined at an angle of 20.8 degrees with respect to the horizontal and has a height of 7.25 m. The sled's blades have recently been greased so that the sled slides down the hill without friction. What is the final speed of the sled (in m/s) just as it reaches the bottom of the hill? Use g = 9.81 m/s2.
A skier starts at the top of a frictionless slope and pushes off with a speed of 3.0 m/s. The elevation of the slope is 40 m. She skis down the slope to a valley with elevation 0.0 m and then glides to the peak of an adjacent slope that is at an elevation of 25 m. Calculate her speed at the second peak

Some gliders are launched from the ground by means of a winch, which rapidly reels in a towing cable attached to the glider. What average power must the winch supply in order to accelerate a 184-kg ultralight glider from rest to 26.2 m/s over a horizontal distance of 53.3 m? Assume that friction and air resistance are negligible, and that the tension in the winch cable is constant. Number i Save for Later Units Attempts: 0 of 3 used Submit Answer
