the answer is option is option (c)
method of solving this problem :
given,
mass= 550 grams = 0.55 kg
velocity = 25 m/s
energy = 1/2 * m * v²
energy = 1/2 * 0.55 * 25 * 25
energy = 1/2 *0.55 * 625
energy = 171.875 J
therefore the answer is 171.875 J which is option (c) .
i hope that my answer will help u ...........................^_^
