Hello,
I found one of my this homework question difficult and was wondering if anyone could please help me.
A 180g trolley is placed on frictionless air track. One end of the trolley is attached to a spring of spring constant 50 N/m. The trolley is pushed against a fixed support so that the compression of the spring is 8 cm. The trolley is then released.
(a) What is the initial acceleration of the trolley when it is released?
(b) What is the initial energy stored in the spring?
(c) Calculate the final speed of the trolley along the frictionless track. You may assume that there is 100% transfer of energy from the spring to the trolley.
Any help would greatly be appreciated.
