Spring is initially at rest in its equilibrium position

Reference no: EM13536898

A mass of 5.0 kg is attached to one end of a spring with a spring constant 80 N/m. The other end is attached to a rigid wall. The spring is initially at rest in its equilibrium position, then a force of 100 N pulls the mass away from the wall, stretching the spring. The coefficient of friction between the mass and the floor is 0.30. What is the speed if the box after it has moved 0.50 m?

What is the angle with respect the x-axis as measured : A meter stick is at rest in a frame S', which is traveling with a speed of V=0.8c with respect to a frame S. The stick makes an angle of 60 degrees with respect to the x-axis as measured by an observer in S'. What is its length and what is the angle ..

How many muons will it register in one hour : The muons created by cosmic rays in the upper atmosphere rain down uniformly on the earth's surface, although some of them decay on the way down, with a half-life of about 1.5?s (measured in their rest frame).

What is the percent difference : A satellite travels at about 8000m/s. What is the factor γ for this speed? As observed from the ground, by how much would a clock traveling at this speed differ from a ground based clock after one hour (as measured by the latter)? What is the percent..

Calculate the delta V for the arrival at the LaGrange point : I am working on a project where we need to find an optimal transfer for a spacecraft from LEO to the L4 LaGrange point in the Earth-Moon system.
