Question

If the percentage error in the measurment of mass m and velocity of v of a body are 15% and 2% respectively. Find the percentage error in the measurement of its momentum and kinetic energy.​

Answer 1

Answer:

17% & 19%

Explanation:

p=mv

error in p =15+2

           =17%

k.e=(mv^2)/2

      =15 +(2*2)

   =19%
