10 A cart is moving horizontally along a straight line with constant speed of 30 m/s. A projectile is fired from the moving cart in such a way that it will return to the cart after the cart has moved 80 m. At what speed (relative to the cart) and at what angle (to the horizontal) must the projectile be fired?
35.8 m/s at 24 degrees
38.6 m/s at 54 degrees
27.2 m/s at 35 degrees
24.3 m/s at 44 degrees
11 A projectile shot at an angle of 60 degrees above the horizontal strikes a wall 25 m away at a point 16 m above the level of projection. What is the magnitude of the velocity with which the projectile hits the wall?
25. 44 m/s
21.11 m/s
11.62 m/s
14.63 m/s
