1. A rock is suspended from a string and moves downward at constant speed. Which statement is true concerning the tension in the string if air resistance is ignored? A) The tension is zero newtons. B) The tension points downward. C) The tension is equal to the weight of the rock. D) The tension is less than the weight of the rock. E) The tension is greater than the weight of the rock. 2. A book is resting on the surface of a table. Consider the following four forces that arise in this situation: ( 1 ) the force of the earth pulling on the book ( 2 ) the force of the table pushing on the book ( 3 ) the force of the book pushing on the table ( 4 ) the force of the book pulling on the earth The book has an acceleration of 0 m/s 2 . Which pair of forces, excluding "action-reaction" pairs, must be equal in magnitude and opposite in direction? A) 1 and 2 B) 1 and 3 C) 1 and 4 D) 2 and 3 E) 2 and 4 Page 2

A car is initially traveling at 50.0 km/h. The brakes are applied and the car stops over a distance of 35 m. What was magnitude of the car's acceleration while it was braking? A) 2.8 m/s 2 B) 5.4 m/s 2 C) 36 m/s 2 D) 71 m/s 2 E) 9.8 m/s 2 4. A 1000-kg car travels along a straight 500-m portion of highway (from A to B ) at a constant speed of 10 m/s. At B , the car encounters an unbanked curve of radius 50 m. The car follows the road from B to C traveling at a constant speed of 10 m/s while the direction of the car changes from east to south. What is the magnitude of the acceleration of the car as it travels from B to C? A) 2 m/s
