Experimental setup of a cart on a horizontal track colliding with a force sensor.
Experimental setup of a cart on a horizontal track colliding with a force sensor.
A cart of mass \(m = 0.50 \text{ kg}\) travels along a horizontal track in the \(+x\)-direction toward a rigid force sensor fixed to a wall. The cart collides with the sensor and rebounds in the \(-x\)-direction. Data for the initial velocity \(v_i\), final velocity \(v_f\), and collision duration \(\Delta t\) for two trials are shown in the table.

TrialInitial Velocity (m/s)Final Velocity (m/s)Collision Duration (s)
1+2.0-2.00.080
2+3.0-1.00.040

How do the magnitude of the impulse delivered to the cart and the magnitude of the average force exerted on the cart in Trial 2 compare to those in Trial 1?
