1. A golf ball is hit from ground level with initial velocity given x(t)= 3 m/s(t) in a direction that is due east and at an angle theta above the horizontal. Neglecting air resistance, use Newton's second law to find the position as a function of time, using coordinates with x measured east and y north. Find the time for the golf ball to return to the ground and how far it travels in that time.
Decont M ts. Using Newton's second law to calculate the acceleration of a key hanging in a car. You tape one end of a piece of string to the ceiling light of your car and hang a key with mass m on the other end of the string, A protractor taped to the light allows you to the angle the string makes with the vertical. Your friend drives the car while you make measurements. When the car has a constant acceleration with magnitude a toward the right, the string hangs at rest (relative to the car), making an angle ß with the vertical.
