In the energy transformation experiment, suppose that you launch the cart uphill from the bottom of the track with a certain initial speed. you now put in a taller riser block and repeat the experiment using the same initial speed of the cart. how will using a taller riser block affect the maximum distance that the cart travels along the track?

Acart with mass 2.0 kg moving on a frictionless linear air track at an initial speed of 1.0 m/s undergoes an elastic collision with an initially stationary cart of unknown mass m. after the collision, the first cart continues in its original direction at 0.6 m/s. let v be the velocity of the second cart after the collision. a) what is the momentum p = mv of the second cart after the collision? b) what is the kinetic energy k = 1 2mv2 of the second cart after the collision? c) divide the equation from (a). what is the velocity v of the second cart after the collision? (b) by the equation from d) what is the mass m of the second cart?
