MASS 500 g FIXED WITH SPRING (a block-spring system) and the other side is fixed with the wall. This mass lay down on the floor without friction between mass and floor. When apply force to pull spring out of equilibrium point (x=0) with displacement 10 cm. Give spring constant = 50 N/m. Calculate - Amplitude. (A) - Frequency of vibration (f) - Period of motion (T) - Velocity when t= 3/4 T -Acceleration when t= 3/4 T
