AP Physics B – Newton’s Laws Questions 6 - 7 A 2-kilogram block slides down a 30° incline as shown above with an acceleration of 2 meters per second squared. 1984B6. Create a free body diagram that best represents the gravitational force W. the frictional force f, and the normal force N that act on the block. 1984B 7. Determine the magnitude of the frictional force along the plane. 1984B 8. A person stands on a rotating merry-go-round. Indicate the direction of the frictional force exerted on the person by the merry-go-round. 1984B11. When the frictionless system shown above is accelerated by an applied force of magnitude F, determine the tension in the string between the blocks. 1984B51. A ball attached to a string is whirled around in a horizontal circle having a radius r. If the radius of the circle is changed to 4r and the same force is applied by the string, compare the new speed of the ball to the original. 1984B61. A push broom of mass m is pushed across a rough horizontal floor by a force of magnitude T directed at angle θ as shown above. The coefficient of friction between the broom and the floor is μ . Determine the frictional force on the broom. Copyright © 1984 by College Entrance Examination Board. All rights reserved.

1984B67. A racing car is moving around the circular track of radius 300 meters shown above. At the instant when the car's velocity is directed due east, its acceleration is directed due south and has a magnitude of 3 meters per second squared. Determine the magnitude and direction of the velocity of the car when viewed from above. 1988B2.
