A 500 g ball is placed on a Hooke's Law spring (k = 20.0 N/m) which hangs vertically from a ceiling. See figure. Initially, the ball is 1.75 m above the floor and the spring is compressed 50.0 cm. When released, the ball moves down. Take y= 0 at ground level. 1.75 m (a) Find the initial elastic and gravitational potential energies. (b) Find the elastic and gravitational potential energies when the spring is at its unstretched (relaxed) length. find...

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.

A spring with a spring constant of 250.0 N/m is mounted horizontally over a frictionless surface. The spring is compressed by 18.5cm to launch a 650g box along the frictionless surface. What is the speed of the box after it is launched?

A massless spring of a spring gun has a force constant k=800 N/m. A ball of mass 0.5 kg is resting on top of the spring. The ball compresses the spring by d as shown in the right figure. When the gun is fired vertically, the ball reached a maximum height of 5 m from the top of the spring as it returns to its natural length. Calculate how much the spring was initially compressed (d). (a) 12 cm; (b)...

A spring with spring constant 28 N/m is compressed a distance of 7.5 cm by a ball with a mass of 201.5 g (see figure below). The ball is then released and rolls without slipping along a horizontal surface, leaving the spring at point A. The process is repeated, using a block instead, with a mass identical to that of the ball. The block compresses the spring by 7.5 cm and is also released, leaving the spring at point A....

A spring is used to fire a 100-g block horizontally. The spring has a spring constant of 20 N/m and is initially compressed by 5.0 cm. The block is initially at rest. a) What is the initial elastic potential energy? b) The spring is released. The block leaves the spring when the spring is at its relaxed state. What is the kinetic energy of the block as it leaves the spring? c) After the block leaves the spring, it enter...

A spring with a spring constant of 718 N/m lies on a horizontal surface and that surface is y = 0 m to calculate the gravitational potential energy. A mass of 3 kg is compressed 0.45 meters into the spring and held still. After the mass is released it slides over a horizontal surface in which a 3.4 meter portion of the surface has friction with a coefficient of kinetic friction of 0.30. After the horizontal surface, it travels up...

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...

3. A spring with a force constant of 7.0 N/m is hung vertically and then compressed by 0.125 m. If a 0.100 kg mass is attached to the spring while compressed by 0.125 m, what will the speed of the mass be when it is passing a point 0.175 m below the compression point (i.e. 0.050 m or 5.0 cm below the equilibrium point)?
A spring with spring constant k is positioned vertically and then compressed from its equilibrium length...
A spring with spring constant k is positioned vertically and then compressed from its equilibrium length by a distance Delta y (Figure 1). A ball of mass m is placed on top of the spring, and is launched into the air when the spring is released (this setup is similar to the projectile launcher seen earlier in the semester). The ball travels to a maximum height h_max. Using the Work-Kinetic Energy theorem, determine h_max in terms of the given variables...
