(solution) The acceleration of a particle is defined by the relation a =

(solution) The acceleration of a particle is defined by the relation a =

The acceleration of a particle is defined by the relation a = kr2.

a) Knowing that v = -8 m/s when t = 0 and that v = +8 m/s when t = 2 s, determine the constant k.

b) Write the equations of motion, knowing also that x = 0 when t = 2 s.

Can I get a good clear explanation to this problem I’m really tryingto understand whats going here
