Question

For an impulse-momentum experiment, students collect data on a collision between blocks A and B . A force probe attached to block A is used to measure the force exerted by block A on block B as a function of time during the collision. The data collected shows a positive force that is used to determine the impulse on block B . The force sensor is removed from block A and attached to block B , and the experiment is run again. Which of the following correctly describes how this affects the data and if the impulse on block B can still be determined?
A. The data can only be used to determine the impulse on block A, not block B.
B. The data can only be used to determine the impulse on block B, not block A.
C. The data cannot be used to determine the impulse on block A or block B.
D. The data can be used to determine the impulse on block B and block A.
E. The data can be used to determine the force on block B.

Answer 1

Answer:

the answer the correct one is D

Explanation:

The relationship between momentum and moment is

         I = Δp

         I = F t

This is for one of the body, that is, the force and the change in speed is for the same body.

In this case, in the first part, the sensor is placed in body A, therefore the force of this body can be measured and as time is also measured, let's calculate the impulse of body A.

In the second part of the experiment, the probe is placed in body B and the experiment is repeated, so we can also calculate the momentum of body b.

consequently in this experiment the momentum of body a and b can be measured.
