A ball is thrown with an initial velocity of 20 m/s at an angle of 60 above the horizontal. What is the horizontal component of its velocity at the top of its trajectory if air resistance is negligible? Question 4 A ball is thrown at an initial speed of 8.0 m/s at an angle of 35 above the horizontal. If there is no air resistance, what is the speed of the ball when it returns to the same horizontal level? 0.16 mc
