A skier leaves the starting gate at the top of a ski jump with an initial speed of 3.00 m/s, as shown in the figure. The starting position is 120 m higher than the end of the ramp, which is 3.00 m above the snow. Find the final speed up of the skier if he lands a distance d = 165 m down the 20.0° slope. Assume there is no friction on the ramp, but air resistance causes a 50% loss in the final kinetic energy. Dy = m/s 120 m 3.00 m d 20
A 15.0-kg suitcase falls from a hot-air balloon that is at rest at a height of 355 m above the surface of Earth. The suitcase reaches a speed of 30.0 m/s just before it hits the ground. Calculate the percentage of the initial energy that is "lost" to air resistance. percentage lost:
