22PRACTICE PROBLEM
Jimmy and his friend make a contraption with a horizontal mass-spring system. In the first trial, they attach a 68 kg mass to the spring and set it to oscillate. Assume the oscillating object's position is given by x = (0.240 m) cos ((π rad/s) × t). At time t = 2 s, how much force does the spring exert on the object?
