Chapter 2: Description of Motion

If you know the acceleration of an object, how do you find its speed and distance traveled at any given time? (Assume straight-line motion, constant acceleration.)

Assuming constant acceleration, show a complete set of motion equations which will describe any motion meeting this condition.

A ball is thrown upward with a velocity of 30 m/s. Find its height and velocity after 1 second. Find its maximum height. Find its total time of flight when it reaches its original height.

Chapter 3: Motion in 2D and 3D

Describe the motion of an object in free fall near the surface of the earth.

If you drop one ball and launch another horizontally at the same time from the same height, will they hit the ground at the same time?

If you fire a bullet horizontally and drop another simultaneously, which will hit the ground first?

Relate the basic set of motion equations to trajectory motion, neglecting air friction.

How can you predict whether the baseball is going to clear the fence? What do you need to know?

Show how a position is specified in terms of unit vectors.

How are velocity and acceleration defined in terms of the vector displacement?

Show how relative velocities are combined to obtain a resultant velocity.
