PHYS2010 EXAM 2, VERSION 0001, SPRING 2006 1 The following two questions refer to the following situation: A cannonball is fired with an initial speed v0 = 100 m/s, at an angle ? = 60? from the horizontal. The cannon is atop the edge of a cliff at a height h above a plain. The cannonball strikes the ground at a distance r from the cliff. In the diagram, three points on the trajectory are labeled: A where the projectile leaves the barrel of the cannon; B at the highest point of the trajectory; and C the point in the air immediately before the ball hits the ground. Air resistance is negligible. 1. The speed of the projectile during its flight is at a maximum at: A) Point A B) Point B C) Point C D) None of these The speed is maximum at Point C. This can be shown by noting that velocity in x is constant, while (absolute value of) velocity in y is maximized at point C. 2. Suppose the cannonball is in the air for 20.0 s. To three-place precision, what is the distance r? A) 1.00 km B) 2.00 km C) 0.707 ...
