Sagot :
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 kg
v = speed of the object = 4 m/s
therefore, 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
OR
K.E = (1600 J)(1 KJ/1000 J)
K.E = 1.6 KJ
