Kinetic energy is the energy possessed by a moving object KE = 1/2 mv^2

m = mass (kg)
v = velocity (m/s)
KE = Kinetic energy (J)

Solve the numerical problem about the kinetic energy by using the formula above
(with working)​

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
