Answer:
Sorry but I don't have a clue about the a) one
b) Given percentage errors in mass and velocity = 2% and 3% respectively
The kinetic energy of the particle is given by
KE =mv²/2
The percentage error in kinetic energy will be
m/Δm×100+2vΔ/v×100
= 2+6
= 8%
This is your answer mate
Hope this helps you!
Purple you!!
Have a great day ahead!!
