sanchez (es25396) – Homework #5 - Projectiles, Net Force, Newton’s 2nd Law – guevara – (130101) 1 This print-out should have 14 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points A basketball player 2 . 02 m tall wants to make a basket from a distance of 10 . 1 m. The hoop is at a height of 3 . 05 m. The acceleration of gravity is 9 . 8 m / s 2 . Neglect air friction. 2 . 02 m 3 . 05 m 10 . 1 m v 0 24 . 7 If he shoots the ball (from a height of 2 . 02 m) at a 24 . 7 angle, at what initial speed must he throw the basketball so that it goes through the hoop without striking the backboard? Answer in units of m / s. 002 10.0 points A ball is thrown straight upward and returns to the thrower’s hand after 3 s in the air. A second ball is thrown at an angle of 31 with the horizontal. The acceleration of gravity is 9 . 8 m / s 2 . At what speed must the second ball be thrown so that it reaches the same height as the one thrown vertically? Answer in units of m / s.
