A ball is thrown off of a 25-m-high cliff. Its initial velocity is 25 m/s, directed at an angle of 53° above the horizontal. How much time elapses before the ball hits the ground? (sin 53° = 0.80; cos 53° = 0.60; tan 53° = 1.3)

1

The velocity–time graph above represents a car on a freeway. North is defined as the positive direction. Which of the following describes the motion of the car?

1

A free-body diagram includes vectors representing the individual forces acting on an object. Which of these quantities should NOT appear on a free-body diagram?

1

An object rolls along level ground to the right at constant speed. Must there be any forces pushing this object to the right?

1

A satellite orbits the moon in a circle of radius R. If the satellite must double its speed but maintain a circular orbit, what must the new radius of its orbit be?

1

A strong hurricane may include 50 m/s winds. Consider a building in such a hurricane. If the air inside the building is kept at standard atmospheric pressure, how will the outside air pressure compare to the inside air pressure?

1

At room temperature, the rms speed of nitrogen molecules is about 500 m/s. By what factor must the absolute temperature T of the Earth change for the rms speed of nitrogen to reach escape velocity, 11 km/s?

1

On which of the following physics principles does Kirchoff 's loop rule rest?

1

The circular wire shown carries a current I in the counterclockwise direction. What will be the direction of the magnetic field at the center of the wire?

1

A traveling wave passes a point. At this point, the time between successive crests is 0.2 s. Which of the following statements can be justified?

1

The state of a gas in a cylinder is represented by the PV diagram shown. The gas can be taken through either the cycle ABCA, or the reverse cycle ACBA. Which of the following statements about the work done on or by the gas is correct?
