Question 1Rotational Kinetic Energy

A satellite is in a circular orbit around the earth and moves at a constant speed. If the height of the orbit above the surface of the earth increased (and the orbit remained circular) the kinetic energy of the satellite would

Question 2Systems and Center of Mass

A person is standing in an elevator which is accelerating upwards. Which of the following is true of the person’s apparent weight?

Question 3Scalars and Vectors in One Dimension

A block is sliding on an incline with negligible friction as shown in the figure above. At time t=0t = 0 s the block is moving up the incline with a speed of 1.5 m/s. The magnitude of the acceleration of the block is a constant 1.0 m/s² down the incline. At t=3t = 3 s, what is the direction of the block’s motion and is the speed increasing or decreasing?

Question 4Systems and Center of Mass

A rock is attached to a 0.4 m long string and is swung through the air so that the path of the rock follows a horizontal circle as shown in the top view figure above. The string makes a 30° angle with the vertical as shown in the side view figure. The rock completes one revolution per second. The speed of the rock is most nearly

Question 5Systems and Center of Mass

A small block slides along a frictionless track with a vertical loop as shown in the figure above. The block is not attached to the track in any way, but its initial velocity is great enough that it moves through the loop without losing contact with the track. What is the direction of the force exerted on the block by the track when the block is at the top of the loop?
