Homework set#1

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.

How are instantaneous velocity and acceleration defined in terms of derivatives?

Given a position as a function of time, how do you find the acceleration?

Given acceleration as a function of time, how do you find the position?

For an object with constant acceleration, show that integration of the acceleration leads to the motion equations for velocity and position.
