Question

Find the percentage error in Kinetic energy of an object having mass m = (10 ± 0.01) kg moving with a velocity of v = (100 ± 0.01) m/s.  ​

Answer 1

Answer:

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

% uncertainty in mass = 0.1/25 = 0.4%

K.E= 1/2 mv^2

K.E = m+ 2V

K.E= 0.5 + 2 x 0.4

K.E= 0.5 + 0.8

K.E= 1.3% uncertainty
