Use the drop-down menus to complete each sentence. To run the simulation, you will alter mass in creating momentum of the carts. The total mass of the carts in the collision is the variable. The velocity of the combined carts after the collision will change because of the change in the independent variable. In this way, the final velocity is the variable.

What is the rate of change in a objects position?

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?

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
