a 4.5 kg block on a horizontal frictionless surface is attached to an ideal spring whose force constant (spring constant) is 450 N. The block is pulled from its equilibrium position at x=0.000 m to a position x=+0.080 m and is released from rest. The block then executes harmonic motion along the horizontal x-axis. The maximum kinetic energy of the system is closest to _____?
A 0.39-kg block on a horizontal frictionless surface is attached to an ideal spring
A 0.39-kg block on a horizontal frictionless surface is attached to an ideal spring whose force constant (spring constant) is 540 N / m. The block is pulled from its equilibrium position at x=0.000 m to a displacement x=+0.080 m and is released from rest. The block then executes simple harmonic motion along the horizontal x-axis. When the block's position is x=0.057 m, its kinetic energy is closest toA. 1.0 J.B. 0.85 JC. 0.80 JD. 0.95 J.E. 1.1 J.

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 block with mass M rests on a
frictionless surface and is connected to a horizontal spring of
force constant k. The other end of the spring is attached to a wall
(Fig. P14.68). A second block with mass m rests on top of the first
block. The coefficient of static friction between the blocks is ms.

A 2.0 kg block on a horizontal frictionless surface is attached to a spring whose force constant is 300 N/m. The block is pulled from its equilibrium position at x = 0 m to a displacement x = + 0.090 m and released from rest t=0 The block then executes SHM along the x-axis horizontal. (a) What is the maximum acceleration and velocity?

wooden block with mass M 3 kg is lying on a horizontal table and is attached to a spring in its equilibrium position. It is hit by a bullet with mass m 5 g which moves horizontally. The bullet remains in the block after colliding with it. The block moves on the table compressing the spring, with spring constant k 50 Nm, a distance 10 cm.

co200.000 10.5 A block of mass 0.5 kg on a horizontal surface is attached to a horizontal spring of negligible mass and spring constant 50 N/m. The other end of the spring is attached to a wall, and there is negligible friction between the block and the horizontal surface. When the spring is unstretched, the block is located at x = Om. The block is then pulled to x = 0.3m and released from rest so that the block-spring system...
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 of mass 2.0 kg is attached to a horizontal spring that has a force constant of 1200 N/m as shown in the figure. The spring is compressed 10.0 cm and is then released from rest as in the figure. (a) Calculate the speed of the block as it passes through the equilibrium position x=0 if the surface is frictionless. (b) Calculate the speed of the block as it passes through the equilibrium position if a constant friction force...
