Answer:
4%
Explanation:
KE = ½mv²
% error in KE =
% error in m + 2× %error in v
=2+ 2×1
=2+2
=4%

Answer:
The percentage error in measuring kinetic energy is 4%
Explanation:
Given that,
The percentage error in measuring mass of a particle is 2%
Therefore,
Also given the percentage error in measuring velocity is 1%
Hence,
The kinetic energy is related with mass and velocity as
Applying error derivative on both sides we get
Multiplying both sides by 100 to get the percentage error,we get
Substituting the given values,we get
Therefore,The percentage error in measuring kinetic energy is 4%
