Question

if there is a +ve error of 50% in the measurements of velocity of a body, find the error in measurements of kinetic energy​

Answer 1

Answer:

225%

Explanation:

K=kinetic enrg

v=velocity

k=1/2mv^2

so,K=V^2 (by error measurement method)

   K=(1.5)^2 (let 1= v then 50% error is 1v +(50/100)v which is 1.5v)

K=2.25v

error %

(2.25-1)*100%=225%
