1 . Compared to Earth's gravitational force on the space shuttle when in orbit, the force on a shuttle astronaut is : a. less because the astronaut has less mass than the shuttle. Earth. b. more because the shuttle was built to orbit, but the astronaut was made to be on c. less because the shuttle pulls him around in orbit. d. the same both are zero because there is no gravity in space. e. the same because both are orbiting at the same speed. 2. A fire hose ejects water at an angle of 35.0 above the horizontal. The water leaves the nozzle at a speed of 25.0m/s. Assuming the stream of water behaves like possible fire? a projectile, how far from the building must the hose be located to hit the highest Round your answer to one decimal place and include units. 3.A ball is kicked at an angle of 32 above the horizontal on a level surface with an initial vertical velocity of 27 m/s. How far does the ball travel horizontally? Round your answer to the nearest whole number and include units. ground 42 m from 4. A rock is thrown horizontally off the top of a 57 m tall building. It hits the from the base of the building. What is the initial horizontal velocity of the rock? Round your answer to one decimal place and include units. 5. A bullet is shot at some angle above the horizontal on a level surface. It travels in the air for 10.4 seconds before it strikes the ground 440 m from the shooter. What was the initial x-velocity (vx) of the bullet? Round your to one decimal place and include units. 6. Romeo is tossing pebbles gently up to Juliet's window, and he wants the pebbles to hit the window with only a horizontal velocity. He is standing at the edge of a rose garden 4.5 m below her window and 5.0 m from the base of the wall. How fast are the pebbles going when they hit her window? Round your answer to one decimal place and include units. 7. A 75 kg ice skater is moving at a constant speed in a horizontal circle of radius 15 meters as he holds onto a rope attached to a pole at the center of the rink. Consider the ice to be frictionless. If the tension in the rope is 350 N, what is the speed of the skater? Use g equals nine. eight m/s for the acceleration of gravity. 8. A bullet is shot at an angle of twenty seven degrees above the horizontal on a level surface. It travels in the air for 12.2 seconds before it strikes the ground 340 m from the shooter. What was the initial y-velocity (vy) of the bullet? Round your answer to one decimal place and add units. 9. A box rests on a level table. Let W be the weight of the box, and N is the normal of the table on the box. In magnitude, W is opposite and N, and the two forces action-reaction pair. a. is greater than, are b. is greater than, are not c. equals, are d. equals, are not
