Force

We chose up and right to be the positive direction. The intial position of the ball is 0.3m. The inital velocity is 0 because it is not in motion yet so it does not have a velocity. The initial force of the ball is 0.1568 N because the force is mass times acceleration. The initial acceleration of the ball is -9.8 m/s2 because that is the force of gravity. It is negative because we chose down to be negative and the ball is moving down. The force and acceleration stay the same because they are constants. Force is 0.1568N and acceleration is -9.8 m/s2..The velocity at 0.01 seconds is -0.098 because final velocity is initial velocity plus acceleration times the change in seconds.     The position of the ball after 0.01 seconds is 0.3 because final position is initial position plus velocity times the change in time. The condition for the ball hitting the table is the acceleration and force change because gravity is no longer causing a change in either. The ball hits the table at 0.25 and 0.26 seconds. When time equals 0 then force equals 0 since there is no force acting on it in the horizontal direction.
