An applied force of 6 Newtons acts in the direction of motion of a block of mass 9 Kg, with the mass being pulled across the floor against a frictional force of .6 Newtons. Assume that the block moved the distance 'y' in this process.
* What is the net force on the object?
* How much work does the net force do on the object?
* How much work does the applied force do on the object?
* What is the work done by the frictional force on the object?
* If the object had initial velocity 6 m/s, and if the force was applied for 3 seconds, then what is its acceleration and by how much did the velocity of the object therefore increase?
* What was its change in kinetic energy?
* How is this change related to the work done by the applied force and the frictional force?
* How is this change related to the work done by the net force?

What velocity did the bullet exit the barrel
: A gun fires a bullet of mass 22 grams out of a barrel 36 cm long. The gun is attached to a spring. From the recoil of the spring and the masses of the gun and the spring we determine that the gun recoiled with a total momentum of 4.7 kg m/s. With ..

Modify your handling of the quantity of items
: Only values in the range 1-99 are accepted. Illegal or out-of-range values cause a reprompt for a valid input. Up to 3 such requests for valid input are made, and the program terminates if a valid numeric in-range quantity is not entered by the cu..
