Q. A 150 ball attached to a spring with spring constant 2.70 oscillates horizontally on a frictionless table. Its velocity is 18.0 when x = -5.00 cm. What is the amplitude of oscillation? What is the speed of the ball when x = 3.00 cm?
Q. A 500g block slides along a frictionless surface at a speed of 0.35m/s. it runs into a horizontal massless spring w a spring constant of 50N/m. how long does the block remain in contact.
