What is the velocity of the mass as it loses contact with the spring? A 1448.0 g mass is on a horizontal surface with mu=0.47? And is in contact with a massless spring with a force constant of 616.0 N/m which is compressed .When the spring is released, it does12.32J of work on the mass while returning to its equilibrium position. Calculate the distance the spring was compressed ,

Initially a 4kg mass and a 2kg mass are at rest on a friction free surface held together by a string. Between these two masses is a spring compressed by 0.1 m. At t= 0 , the string is cut and the two masses allowed to fly apart. When the masses are far apart, the velocity of the 2kg mass is 2m/s. 1) What is the velocity of the 4kg mass?? 2) Is momentum conserved in this process, i.e is...

A 2.1 kg mass is attached to a spring with a spring constant of 75.3 N/m. The spring is securely attached on the other end to a vertical wall so that the spring extends and contracts horizontally. The mass is shoved so the mass has a velocity of 3.1 m/s and the spring is streched 0.128 m from its equilibrium, or rest, position when the mass is released. Friction and air resistance are negligible. What is the greatest distance that...

Incline, Spring, and Friction: A block of mass 500 g is attached to a spring of spring constant 80 N m−1. The other end of the spring is attached to a support while the mass rests on a rough surface with a coefficient of friction of 0.20 that is inclined at angle of 30◦ . The block is pushed along the surface till the spring compresses by 10 cm and is then released from rest. (a) Compute how much potential...

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 spring-block system sits on a horizontal, frictionless surface. The spring has a spring constant k =2000N/m. The blocks mass is 10.0kg. The mass of the spring is negligible. The spring is stretched out a distance of 20.0 cm and released. The block undergoes simple harmonic motion with a phase constantf= 1.35 rad. a) determine the timeit takes for the spring to be compressed 6.50cm after it was released b) determine the acceleration of the black at t = 1.50 s.
