A 4.00-kg particle moves along the x axis. Its position varies with time according to x = 3.0t + 2.0t^2 where x is in meters and t is in seconds. Find
a) the kinetic energy at any time t,
b) the acceleration of the particle and the force acting on the particle,
c) the power being delivered to the particle at any time t,
d) the work done on the particle in the interval t = 0 to t = 2.00 s.
