A 200 kg object is going 4m/s. Find its kinetic energy

Answer:The Kinetic Energy of the given object of mass 200 kg, traveling at 4 m/s is found to be 1600 J (OR) 1.6 KJ. Explanation:The generalized formula to find the Kinetic Energy of a body, that is in motion, is as follows:Kinetic Energy = K.E = (1/2)mv²   _____________  eqn (1)where,m = mass of the object = 200 kgv = speed of the object = 4 m/stherefore, substituting these values, in eqn (1), we find the kinetic energy of the given object, as follows:eqn (1) =>K.E = (1/2)(200 kg)(4 m/s)² K.E = 1600 J ORK.E = (1600 J)(1 KJ/1000 J)K.E = 1.6 KJ

KE = 1/2mv^2     =1/2(200)(4)^2     =100(16)     = 1600 J
