A 0.2kg rock attachedd to a horizontal springg of spring constant k=200N/m is placed on a horizontal, frictionless surface. The rock is then pulled to the right do that the spring stretches a distance of 0.10m. The block is released at time t=0s and undergoess simple harmonicc motion.
A) what is the amplitude of motion for the rock?
B) what is the frequency of the motion?
C) what is the maximum velocity of the rock?
D) what is the maximum acceleration of the rock?
E) what is the total mechanical energy of the system at any instant?
F) what is the speed of the rock each time the spring is stretched 5cm?
G) what is the acceleration of the rock each time the spring Is stretched 5cm?
