A cart collides into a rubber band. Which statements best describe how energy is being converted/transferred during the time when the cart is slowing down and the band is stretching?
1 Kinetic energy is being converted into elastic potential energy
2. Elastic potential energy is being converted to kinetic energy
3. Energy is transferred from the cart to the band.
4. Energy is transferred from the band to the cart.
5. No energy conversions are taking place.

Since the pully is a simple machine so the mechanical advantage is a 1

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
