*74. D In a stunt being filmed for a movie, a sports car overtakes a truck towing a ramp, drives up and off the ramp, soars into the air, and then lands on top of a flat trailer being towed by a second truck. The tops of the ramp and the flat trailer are the same height above the road, and the ramp is inclined 16° above the horizontal. Both trucks are driving at a constant speed of 11 m/s, and the flat trailer is 15 m from the end of the ramp. Neglect air resistance, and assume that the ramp changes the direction, but not the magnitude, of the car's initial velocity. What is the minimum speed the car must have, relative to the road, as it starts up the ramp?

X Incorrect In a basketball game, the point guard A intends to throw a pass to the shooting guard B, who is breaking toward the basket at a constant speed of 11 ft/sec. If the shooting guard is to catch the ball at a height of 7.1 ft at C while in full stride to execute a layup, determine the speed vo and launch angle with which the point guard should throw the ball.

A baseball is hit at an angle 0 and travels along a parabolic arc before it strikes the ground. Which one of the following statements is true? O The acceleration of the ball decreases as the ball moves upward. O The velocity of the ball is O when the ball is at the highest point in the arc. O The acceleration of the ball is 0 when the ball is at the highest point in the arc. O The velocity of the ball is a maximum when the ball is at the highest point in the arc. O None of the above.

Which of the following statements about the rock's motion are true just before it hits the ground? O Its horizontal velocity component is zero. O Its horizontal velocity component is the same as it was just as it was launched. O Its speed is the same as it was just as it was launched. O Its velocity is vertical.

A small child is learning to ride a bike for the first time. Her dad decides it would be a good idea to start her on a small hill. The hill is inclined at 3.00° to the horizontal. The child starts partway down the hill, 9.00 m away from her dad, who stays at the top. She starts to wobble, so her dad sprints toward her from rest with an acceleration of 1.40 m/s2. How far has the child gone before her parent catches her?
