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.

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
