As shown in the figure below, a ski jumper leaves the ski track moving horizontally with a speed of vi=20m/s. The landing track below her is an incline at an angle of θ=37∘ to the horizontal. The horizontal distance the jumper travels before she lands on the incline is A 120m B. 100m C. 75m D. 60m E. 45m Ans: D
A stone is thrown from ground level at an angle of θ above the horizontal such that the ratio of the x-component of its initial velocity to the y-component of its initial velocity is 2 . The stone strikes a wall 6m away and at a height of 2m above the ground. Calculate the initial speed of the stone. A. 25m/s B. 30m/s C. 10m/s D. 20m/s E. 15m/s
