AP Physics 1
4.2 Change in Momentum and Impulse
Four identical carts, initially at rest on a horizontal frictionless track, each experience a horizontal net force pulse that changes the momentum of each cart by the same magnitude \( \Delta p_0 \). The shape and duration of each force-time pulse are described in the table.
Which of the following correctly ranks the maximum magnitude of the force, \( F_{\max} \), exerted on each cart during its respective pulse?
| Cart | Pulse shape | Duration |
|---|---|---|
| W | Constant force | \( T_0 \) |
| X | Triangular (starts and ends at zero) | \( T_0 \) |
| Y | Constant force | \( 2T_0 \) |
| Z | Triangular (starts and ends at zero) | \( 2T_0 \) |
Which of the following correctly ranks the maximum magnitude of the force, \( F_{\max} \), exerted on each cart during its respective pulse?
