4. Set an object (anyone you choose) to be moving at a constant speed. Describe the procedure for keeping the object moving at a constant speed. Write down the speed at
which the object is moving, as well,
5. Using the equations of constant acceleration, estimate the time for the object to stop
moying once you remove all the applied force. Keep in mind you know the
acceleration of the box because the force of friction is the only force once the figure
stops pushing on the box! Show all your calculations and work to receive full credit

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?
