1.) A ball of mass 0.1kg is thrown straight up with an initial velocity of 19.6 m/s. in answering the following, neglect air resistance and only consider times after the ball has left the hand of the person throwing it.
a.) Draw a free-body diagram of the ball indicating the directions and sources of all of the forces acting on it. To indicate sources, it suffices to use appropriate subscripts on the symbol you choose to represent the magnitude of that force or appropriate symbols for forces that have standard symbols.
b.) List the magnitudes and the directions of all of the forces on the ball
c.) Find the magnitude and direction of the net force on the ball.
d.) Find an expression for the ball's acceleration as a function of time. Then use your expression to find the magnitude and direction of the acceleration after 3 seconds.
