A 4.00 kg cart is pushed against a spring at point A, compressing the spring (with a spring constant of 600 N/m) by 0.816 m. When the cart is released from rest, it moves to the right with a constant speed (assume there is no friction in the wheels). What is the speed of the cart after it is released at point B?

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
