To model jumping we will split the motion into two parts. For the first part, you crouch and make a displacement up by pushing your feet against the ground. The second part is after your feet leave the ground. For the first part, assume that you create an acceleration of 20.4 m/s 2 while your feet are in contact with the ground and that you make a displacement of 0.2 m. 1. What is your velocity when your feet leave the ground? 2. After your feet leave the ground, what kind of motion do you follow, constant acceleration or constant velocity? State the velocity or acceleration. 3. What is your velocity at your maximum height? 4. Determine how high you go after your feet leave the ground.
