The percentage errors in the measurement of mass and speed are 2 % and 3% respectively.how much wil be the maximum error in the estimate of kinetic energy obtained by measuring mass and speed?(adsbygoogle = window.adsbygoogle || []).push({});

its ans is 8 % ..

according to this equation K = mv^2/ 2 , so dK / K = dm/m + 2dv / v

( d means delta ) .. but the problem is , where dat second equation has been derived from? plz help
