I need help desperatley with this problem. Sam (65 kg) takes off (from rest) up a 50 m high, 10° frictionless slope on his jet-powered skis. The skis have a thrust of 160 N. He keeps his skis tilted at 10° after becoming airborne. How far does Sam land from the base of the cliff? I believe I'm almost there but I'm stuck towards the end. Any help would be nice.
