[SOLVED] A ski jumper competing for an Olympic gold-medal wants to jump a horizontal distance of 135 m the take off point of the ski jump is that a height of 25 m with what horizontal speed must he leave the jump

Time before landing = sqrt ( 2 x height / gravity ), sqrt ( 2 x 25 / 9.81) = 2.26distance / time = avg speed135 / 2.26 = 60~ m/s
