A friend drops a medicine ball so that it falls straight down. You catch it. Consider the motion of the ball from the instant it touches your hands (the ball’s downward speed starts to decrease) until the instant it stops (your hands have moved lower with the ball while stopping it).
a. Sketch the process from the instant the ball touches your
hands until the instant it stops. Choose the ball as the system
object of interest.
b. Construct a motion diagram for the stopping process.
c. Construct three force diagrams for the ball for three different
instances during the motion. Be sure each force diagram is
consistent with the motion diagram.
d. What object exerts a bigger force on the ball as you are stopping it – you or Earth?

. Let us examine a ball in the process of bouncing off of a floor. As we discussed briefly in class, if the ball has spin then this is a very complicated problem. So let us assume that the ball has no spin for the duration of the bounce. The ball hits the floor going vertically down. (a) Draw a motion diagram showing the motion of the center of mass of the ball during the bounce. We are only interested...

Questions 2-8 refer to the following: You and your 60 kg workout partner, Kim, are tossing a 4.0 kg medicine ball back and forth to each other. Shortly before she releases the ball, Kim is in the air (her feet are off the ground). At this instant, the only forces she exerts against the ball are a 200 N horizontal force directed forwards and a 250 N force directed upwards. These forces and gravity are the only forces acting on...

1.) A ball with mass 5.0 kg is launched upwards towards the east into the air with a speed of 15. m/s at an angle of 30 degrees to the ground. Note: For this question the motion is fully three-dimensional. Orient your axes so that the positive y-axis points north, the positive X-axis points east, and the positive z-axis points upwards (towards the sky. 1A.) If a gusting...

Question 2 According to Newton's Laws of Motion, if I throw a baseball in outer space - far from any other object- how will that ball move over time? (For the sake of this problem, let's neglect my mass) After the force of my hand no longer acts on the ball: Question 2 options: the ball will move forward, but it will gradually slow down and come to a stop once the force of my hand no longer acts on...
