A block A of mass m is performing SHM of amplitude a. Another block B of mass m is gentle placed on A at the distance of a/2 from the equilibrium position. Find the period and the amplitude of the new system. ​

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.
