Q7/ A particle of mass 7 kg moves along the y-axis. Its position varies with time according
to equation y = 4t5 + 3t* + 2t³ +t² + t+1,where y in meter and t in second. Find:
a- The acceleration of the particle and the force acting on it at time t.
b- The power being delivered to the particle at time t.
c- The change of kinetic energy and the work done on the particle in the interval t=3 to
t=5 sec.
