Chapter 4, Problem 81EAP

In one contest at the country fair, seen in FIGURE CP4.81, a spring-loaded plunger launches a ball at a speed of 3.0 m/s from one corner of a smooth, flat boar that is titled up at a 20° angle. To win, you must make ball hit a small target at the adjacent corner, 2.50 m away. AT what angle ( should you tilt the ball launcher?

A 2.00-m-tall basketball player is standing on the floor 10.0 m from the basket, as in Figure P3. 58. If he shoots the ball at a 40.0° angle with the horizontal, at what initial speed must he throw the basketball so that it goes through the hoop without striking the backboard? The height of the basket is 3.05 m.

A hollow plastic ball is projected into the air. There is significant air resistance opposing the ball’s motion, so the magnitude of the ball’s acceleration is not equal to g. At time t, the ball is moving up and to the right at an angle of 45° to the horizontal, as shown above. Which of the following best shows the magnitude a and the direction of the ball’s acceleration at time t? a C b A c B d D

Olympus Mons on Mars is the largest volcano in the solar system, at a height of 25 km and with a radius of 312 km. If you are standing on the summit, with what initial velocity (in m/s) would you have to fire a projectile from a cannon horizontally to clear the volcano and land on the surface of Mars? Note that Mars has an acceleration of gravity of 3.7 m/s2. (Assume the volcano is radially symmetric and the summit is at its center. Enter the magnitude.)
