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.

Part A
Block A in the figure (Figure 1) has mass 1.00 kg, and block B has mass 3.00
kg. The blocks are forced together, compressing a spring S between them; then
the system is released from rest on a level, frictionless surface. The spring, which
has negligible mass, is not fastened to either block and drops to the surface after
it has expanded. Block B acquires a speed of 1.40 m/s.

A spring clamped to the table shoots Block 1 (110 g, wood) directly into Block 2 (80 g, steel), this perfectlyelastic collision will launch the second block up a ramp. When the spring is compressed 14 cm, the block travels upa ramp that has a height of 86 cm and then compresses another spring (310 N/m) at the top, 5 cm. What then isthe spring constant for the first spring? Assume that all surfaces are frictionless
A block with a mass 3.7 kg is sitting on a frictionless ramp with a spring at rhe bottom that has a spring constant of 540 N/m. The angle of the ramp in respect to the horizontal is 36 degrees. 1) the block starts from rest and slides down the ramp a distance of 69cm before hitting the spring. how far is the spring compressed as the block comes to momentary rest? 2) after the block comes to rest the spring pushes the block back up the ramp. how fast is the block moving right after it comes off the spring. 3) what is the change in gravitational potential energy between the original positiion of the block at the top of the ramp and the position of the block when the spring is fully compressed?
O Macmillan Learning A ball of unknown mass m is tossed straight up with initial speed v. At the moment it is released, the ball is a height h above a spring-mounted platform, as shown in the figure. The ball rises, peaks, and falls back toward the platform, ultimately compressing the spring a maximum distance d from its relaxed position. Assume that the spring is perfectly ideal, with spring constant k, and that the mass of the spring and platform is negligible. What is the mass of the ball, m, assuming that there is no friction or air resistance? Using g to represent the acceleration due to gravity, enter an expression for m in terms of g, h, d, k, and v. m = ||N|- =-= kxx ² gh kg m V h th kogum

A sky diver plans to bungee jump from a tower 74.0 m above the ground. She plans to use a uniform elastic cord, tied to a harness around her body, to stop her fall at a point 11.0 m above the water. Model her body as a particle and the cord as having negligible mass and obeying Hooke's law. In a preliminary test she finds that when hanging at rest from a 5.00 m length of the cord, her body weight stretches it by 1.25 m. She will drop from rest at the point where the top end of a longer section of the cord is attached to the tower. (a) What length of cord should she use? m (b) What maximum acceleration will she experience? m/s²
