​

Answer 1

Answer:

Percentage errors in the measurement of mass and speed are 2% and 3%, respectively. The error in

the estimation of kinetic energy obtained by measuring mass and speed will be

Explanation:

2/100=0.02

3/100=0.03

Answer 2

ANSWER

Given percentage errors in mass and velocity = 2% and 3% respectively

The kinetic energy of the particle is given by

KE =

2

mv

2

The percentage error in kinetic energy will be

m

Δm

×100+2

v

Δv

×100

= 2+6

= 8%
