a student wants to determine the impulse delivered to the lab cart when it runs into the wall. the student measures the mass of the cart and the velocity of the cart before it hits the wall. what other measurement is necessary to calculate the impulse delivered to the lab cart? the velocity of the cart after it hits the wall the force exerted on the cart by the wall the time the cart is in contact with the wall the acceleration of the cart before it hits the wall

Answer

Explanation:

Step1: Recall impulse - momentum theorem

Impulse (J) is equal to the change in momentum (\Delta p). The formula for momentum is (p = mv), and (\Delta p=m\Delta v=m(v_f - v_i)), where (m) is mass, (v_i) is initial velocity and (v_f) is final velocity. The student already has (m) and (v_i), so needs (v_f).

Answer:

the velocity of the cart after it hits the wall
