A 0.156 toy is undergoing SHM on the end of a horizontal spring with force constant 306 . When the object is 1.50×10?2 from its equilibrium position, it is observed to have a speed of 0.300 . Find the total energy of the object at any point in its motion Find the amplitude of the motion. Find the maximum speed attained by the object during its motion.
A toy cork gun contains a spring whose spring constant is 10.02 N/m. The spring is compressed 5.0 cm and then used to propel a 6.00 g cork. The cork, however, sticks to the spring for 1 cm beyond its unstretched length before separation occurs. The m..
