Find the percentage error in kinetic energy of a body having mass 60.0  0.3 g moving with a velocity 25.0  0.1 cm/s.

$\huge\red{\underline{{\boxed{\textbf{ANSWER}}}}}$

%Uncertainty in mass= 0.3/60 x100 = 0.5%

% uncertainty in mass = 0.1/25 = 0.4%

$K.E= \frac{1}{2} m {v}^{2}$

K.E = m+ 2V

K.E= 0.5 + 2 x 0.4

K.E= 0.5 + 0.8

K.E= 1.3% uncertainty.
