A crate is given an initial push on a horizontal floor and is imparted with an initial velocity of 5.0 m/s. Because of kinetic friction, the crate slows down and comes to stop with constant deceleration over a time period of 1.1 seconds. The mass of the crate is 5.0kg. what is the magnitude of the friction force that causes the crate to come to a stop? what is the coefficient of kinetic friction? (Assume that friction is the only...

A 425 g shuffleboard disk is given an initial speed of 3.20 m/s across a horizontal court. The disk travels 0.00 min a straight line before coming to rest assume the acceleration of the disk is constant a) Draw a simple picture; draw the free body diagram for the disk. Identify the coordinate system you are using, that is, what is the direction of the positive x axis? b) What is the net force exerted on the disk while it...

The collar of mass m = 3.7 kg slides on the rough
horizontal shaft under the action of the force F of
constant magnitude F = 24 N but variable direction. If
θ = 0.63t, and if the collar has a speed
v1= 1.9 m/s to the right when θ = 0,
determine the velocity v2 of the collar when
θ reaches 90°. Also determine the value of F
which renders v2 = v1. The
coefficient of friction is μk...

A small block with mass 0.0375 kg slides in a vertical circle of radius 0.600 m on the inside of a circular track. During one of the revolutions of the block, when the block is at the bottom of its path, point A, the magnitude of the normal force exerted on the block by the track has magnitude 4.05 N . In this same revolution, when the block reaches the top of its path, point B, the magnitude of the...
determine the magnitude of the normal force which the curved rod exerts on one collar at the instant θ=110°
Rod O A rotates counterclockwise with a constant angular velocity of θ=5 rad / s. The double collar B is pin-connected together such that one collar slides over the rotating rod and the other slides over the horizontal curved rod, of which the shape is described by the equation r=1.5(2-cosθ) ft. (Figure 1)Part AIf both collars weigh 0.80 lb, determine the magnitude of the normal force which the curved rod exerts on one collar at the instant θ=110° . Neglect...

A small block of mass m is at rest on a table. The coefficient of friction between the block and the table is mu. (The coefficient of static friction is equal to the coefficient of kinetic friction in this problem.) A horizontal force is applied at t = 0 which has magnitude beta t where beta is a known constant. Find the block's velocity as a function of time. Free Body Diagrams (If appropriate). Law or Definition

A block of wood of mass m = 1kg is pushed with an initial velocity of 1m/s down a ramp that makes an angle of 30 degrees with the horizontal. The coefficient of kinetic friction is 0.6. How far along the ramp does it slide before coming to rest?

A block of mass m = 4.50 kg slides along a horizontal table with velocity vo = 5.00 m/s
A block of mass m = 4.50 kg slides along a horizontal table with velocity vo = 5.00 m/s. At x = 0, it hits a spring with spring constant k = 42.00 N/m and it also begins to experience a friction force. The coefficient of friction is given by μ = 0.400. How far has the spring compressed by the time the block first momentarily comes to rest? Assume the positive direction is to the right.

A small block with mass 0.0475 kg slides in a vertical circle of radius 0.0730 m on the inside of a circular track. There is no friction between the track and the block. At the bottom of the block's path, the normal force the track exerts on the block has magnitude 3.70 N. What is the magnitude of the normal force that the track exerts on the block when it is at the top of its path?
