Academics

Q. Sam (85 kg) takes off up a 50-m-high, 10° frictionless slope on his jet-powered skis. The skis have a thrust of 240 N. He keeps his skis tilted at 10° after becoming airborne. How far does Sam land from the base of the cliff?

Q. A 70.0 kg snowboarder has an initial velocity of 6.00 m/s at the top of a 26 degree incline. after sliding down the 100m incline with coefficient of kinetic friction .200 the snow boarder obtained a velocity v at which point he moves along a horizontal field with a coefficient of kinetic friction .140 and stops. what is the net work done on the snow boarder during his trip down the hill and what is his velocity at the bottom of the hill?
