Sam (65 kg ) takes off up a 50-m-high, 10° frictionless slope on his jet-powered skis. The skis have a thrust of 220 N . He keeps his skis tilted at 10° after becoming airborne, as shown in the figure.  How far does Sam land from the base of the cliff? Express your answer to two significant figures and include the appropriate units.
