Problem 2 A block A of 0.5-kg rests on a horizontal, frictionless surface. The block is pressed back against a spring having a constant of k 400 N/m, compressing the spring by 12.0 cm. Then the b sreleased. The incline has a friction coefficient μ-02, and the horizontal surface has no friction. 1. Find the maximum distance d the block travels up the incline if -40 (Position C) 2. How fast is the block moving up when halfway to its...

An object of mass m = 1.70 kg is travelling on a horizontal surface. The coefficient of kinetic friction between the object and the surface is muk = 0.200. The object has speed v = 1 .35 m/s when it reaches x = 0 and encounters a spring. The object compresses the spring a distance d/2, stops instantaneously, and then travels back to x = 0 where it stops completely. Eventually you will be asked to find the spring constant,...

A 1.3 -kg block slides along a horizontal surface with a
coefficient of friction μk = 0.274. The block has a speed v = 2.28
m/s when it strikes a massless spring head-on.
a. If the spring has a force constant k = 30.9 N/m, how far is
the spring compressed?

A block of mass m = 3.5 kg is
on an inclined plane with a coefficient of friction
μ1 = 0.31, at an
initial height h = 0.53 m above
the ground. The plane is inclined at an angle θ =
54°. The block is then compressed against
a spring a distance Δx = 0.11 m

k1 = 39 N/m) and
released. At the bottom of the inclined plane...

Problem 2 A 0.5-kg block is pressed a distance d against a horizontal spring of constant 800 N/m. The block sits on a frictionless horizontal surface When the block is released from rest, it slides along the surface, its speed is 1.6 m/s when it leaves the spring (a) Calculate distance d. 4 cm Suppose that the sliding block (speed 1.6 m/s) crosses a rough section of the surface. The leugth of the section is 1m. The block has a...
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h.
As shown in the figure below, a 2.25-kg block is released from rest on a ramp of height h. When the block is released, it slides without friction to the bottom of the ramp, and then continues across a surface that is frictionless except for a rough patch of width 15.0 cm that has a coefficient of kinetic friction μk = 0.520. Find h such that the block's speed after crossing the rough patch is 4.20 m/s. An object with a...

A block sliding to the right along a horizontal frictional surface has an initial velocity of 12.4 m/s and stops in 110 m due to friction with the surface. Find the acceleration of the block. Find the coefficient of kinetic friction between the block and the surface.

You push a 4.3 kg block against a horizontal spring, compressing the spring by 16 cm. Then you release the block, and the spring sends it sliding across a tabletop. It stops 69 cm from where you released it. The spring constant is 120 N/m. What is the coefficient of kinetic friction between the block and the table?
A block of mass is placed on a horizontal surface and attached to the free end...
A block of mass is placed on a horizontal surface and attached to the free end of a spring. When the spring is neither stretched nor compressed, it exerts no force on the block. When the block is displaced from this position the force on it due to the spring is equal to 250 N/m times the distance the block is displaced. If the coefficient of static friction between the block and the surface is 0.24, how far from this...

A block is resting on a horizontal surface. The mass of the block is 40 kg. The coefficient of static friction between the block and the surface is us = 0.3 and the coefficient of kinetic friction is uk = 0.20. A man then decides to push on the block with 30 newtons of horizontal force. a) What is the acceleration of the block? Explain. b) Suppose the man pushes on the block with 200 newtons instead. What is the...
