A block of mass ?=2.00 kg slides along a horizontal table with velocity ?0=3.50 m/s ....

A block of mass ?=2.00 kg slides along a horizontal table with velocity ?0=3.50 m/s . At ?=0 , it hits a spring with spring constant ?=42.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by ?=0.300 . How far has the spring compressed by the time the block first momentarily comes to rest? Assume the positive direction is to the right.

Expert Solution

To solve this problem I used the law of conservation of energy.

In this case the initial kinetic energy must be equal to the sum of energy loss due to friction and the potential energy gained by the spring.

The length can not be (-)ve so I took the positive part of the quadratic solution.

Starting with a speed of 2.50 m/s, a 2.00 kg block slides across a rough horizontal surface until it collides with a spring. The spring compresses a distance of 6.00cm as the block comes momentarily to rest. The total distance traveled by the block from its starting position to the position where it comes to rest is 0.800m. If the coefficient of kinetic friction between the block and the surface is 0.100, what is the spring constant of the spring?

The diagram below shows a block of mass m = 2.00 kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1 = 4.00 N, F 2 = 6.00 N, and F 3 = 8.00 N are applied to the block, initially at rest on the surface, at angles shown on the diagram. In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles...
