1.	A body of mass 10 kg moving at a height of 2 m, with uniform speed of 2 m/s. Its total energy is
Answer» Kinetic energy= 1/2mv^2= 1/21022=20joulePotential energy=mgh= 109.8*2= 196 jouleTotal energy= 196+20=216 joule<br>Kinetic energy = 1/2 mv^2 = 10 × (2) ^2 /2 = 200 J. // Potential energy = mgh = 10 × 9.8 × 2 = 196 J. Therefore, total energy = 200 + 196 = 396 J. //
