Happy/Sad Ball Lesson Plan
... larger total force to both stop the current motion and reverse it. ● Looking at each ball’s momentum before and after the collision will show this. Both balls have the same mass and were released from the same height, meaning that at the point just before impact they have the same momentum. After th ...

... A 60.0-kg person running at an initial speed of 4.00 m/s jumps onto a 120-kg cart initially at rest (Figure below). The person slides on the cart’s top surface and finally comes to rest relative to the cart. The coefficient of kinetic friction between the person and the cart is 0.400. Friction betw ...

The – sign indicates that the force is directed opposite to the tension or compression of the spring. • The ENERGY stored in a spring is equal to ½ the force times the distance, or V(r) = 1/2 k (r-ro)2 – Note that the sign now does not matter since the dista ...
