  1. Assume that the ball can get to y =10 m. How much kinetic energy does the ball lose in going from y = -10 m to y = 10 m? Is this independent of v0x initial?

i. KE -10= , KE+10=

ΔKE=

  1. What is the work done by gravity when the ball goes from y= -10 m to y = 10 m?
    1. To calculate the work done by gravity first show using symbols only, then determine a numerical value (ie plug numbers into your formula).

Wg= Wg =

(symbols) (number)

We want to look at several ways that we can find the kinetic energy of an object.   One method is to find the velocity of the object, and then use K=1/2mv2   Another method is to find the work done, which tells us by how much the kinetic energy has changed. A ball of mass 2 kg starts from rest. Find its final Kf for each example.   It is accelerated at 5 m/s2 for 2 s.   64 J   100 J   200...
