Question

A skier skis horizontally over the edge of an 8 m cliff with a velocity of 15 m/s How long is she in the air How far away from the cliff does she land What is her speed of impact with the snow If she jumps upwards when she leave the cliff and jumps at an angle of 15 degrees with same 15 m/s velocity then how much higher than the edge of the cliff does she fly?

Explanation / Answer

u = velocity of projection = 15 m/sec ? = angel of projection = 15 degree time of flight = T = 2*u*sin ? /g putting values we get = T = 0.8 sec ---------------------------Ans
