Question

Find the% error in the kinetic
erergy in the body of mass m=
(60-+0.3) and moving with
relocity v= (25.0+ 0.1) cm/s​

Answer 1

Explanation:

The % uncertainty in mass = 0.3/60×100=0.5%

and % uncertainty in mass = 0.1/25×100=0.4%

KE =

mv

KE = m + 2v

KE = 0.5 + 2×0.4

KE = 1.3% uncertainty.

Hope it helps...........
