A spring-block system sits on a horizontal, frictionless surface. The spring has a spring constant k =2000N/m. The mass of the block is 14.5 kg. The spring is stretched out a distance of 20.0 cm and released. The block undergoes simple harmonic motion with a phase constant φ=?. a) if the velocity of the block is -2.00 m/s at t= 0.150 s, what is the phase constant? b) determine the acceleration of the block at t = 0.150 s. c) what...

Elastic Collision Question 8 A 2 kg ball initially at rest rolls down a 30-degree inclined plane from a height of 4 meters (assume kinetic and rolling friction are negligible). A 2 kg box initially at rest slides down a 30-degree directionless inclined plane from a height of 4 meters. How do the velocities of the ball and the box compare when they both reach the bottom of their respective inclined planes?...
