We’re measuring the velocity to so that we can find the change in kinetic energy; so where should you place the photogate to measure the cart’s velocity? Briefly explain your reasoning.

Respuesta :

Answer:

Directly after the cart.

Explanation:

The photogate should be placed in a position directly after the cart, so that the photogate can record the initial velocity of the cart. With this set up, the final velocity is taken to be zero and simplify our calculations.
