Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

**Text:**

A box of mass \( m \) is pressed against (but is not attached to) an ideal spring of force constant \( k \) and negligible mass, compressing the spring a distance \( x \). After it is released, the box slides up a frictionless incline as shown in the figure and eventually stops. If we repeat this experiment but instead compress the spring a distance of \( 2x \).

**Diagram:**

- The diagram shows a smooth horizontal surface with a spring on the left and a box of mass \( m \) adjacent to it.
- The spring is compressed by a distance \( x \).
- The surface and inclined incline are labeled "Smooth," indicating no friction.
- The incline slopes upward from left to right, with the spring positioned at the base.

**Questions:**

- ⚪ the box will go up the incline twice as high as before.

- ⚪ just as it moves free of the spring, the box will be traveling twice as fast as before.

- ⚪ just as it moves free of the spring, the box will be traveling four times as fast as before.

- ⚪ just as it moves free of the spring, the box will have twice as much kinetic energy as before.

- ⚪ just before it is released, the box has twice as much elastic potential energy as before.

Mr. M pushes a box, that has a mass of 2.5 kg against a spring (k=1234 N/m) that is attached to a wall so that it compresses 14 cm and is at rest. The surface the spring is attached to is on a level 0.55m above the ground (refer to diagram). Once the block leaves the block, it encounters friction on the surface. The length of the surface is 1.5m and has a coefficient of friction of 0.11. Once it leaves the frictional surface, the box travels DOWN a frictionless ramp onto a level surface on the ground. How fast is the block going when it gets to the level surface?
A heavy crate (m = 23 kg) is resting on a frictionless inclined plane while suspended from a wall by a spring.The plane is inclined at an angle of 30◦ from the horizontal, and the spring is stretched from its equilibriumposition by 25 cm.

If the frictionless inclined plane is now replacedwith an otherwise identical plane except with a rough surface, the crate now stretches the spring by 12 cmfrom its equilibrium position. What is the coefficient of static friction? You can assume that the staticfriction is at its maximum value.

A spring gun shoots out a plastic ball at speed v. The spring is then compressed twice the distance it was on the first shot.
It will launch a 25 g projectile to a range of 2.15 m when it is launched at an angle of 45 degrees. You can use this information to find the initial velocity of the ball, of course, (and you should). Therefore, you should be able to calculate how much energy the spring in the projectile launcher must impart to the ball as it is being launched. The ball is pushed back 7.5 cm in the projectile launcher in order to getit ready to fire. What is the spring constant of the projectile launcher?
