1. The problem statement, all variables and given/known data For momentum, what should i determine the final velocity if there is a deceleration or acceleration? should i use the kinematic equation to determine the velocity in the case? however, if i'm required to find momentum after the object is already traveled a certain distance? Questions: 1. How fast can you set the Earth moving? In particular, when you jump straight up as high as you can, what is the maximum recoil speed that you give to the Earth? Let your mass be 70.0 kg and your maximum jump height be 0.500 m. Model the Earth as a perfectly solid object. 2. A ball of mass 0.100 kg is dropped from rest from a height of 1.25 m. It rebounds from the floor to reach a height of 0.840 m. What impulse was given to the ball by the floor? how do i define the velocity for mv, because the velocity is not constant due to the gravitational force.
