Question

The percentage error of velocity and mass are 2%and 4% respectively.what is the percentage error in kinetic energy?
​

Answer 1

Answer:

8%

Explanation:

$\sf\bigstar\:Given:$

Percentage of error in velocity = 2%

Percentage of error in mass = 4%

$\sf\bigstar\:To\:find:$

Percentage error in kinetic energy = ?

$\sf\bigstar\:Solution:$

We know, K.E = 1/2mv²

$\implies$ K.E = 1/2 × 4% × (2%)²

$\implies$ K.E = 2% × 4%

$\implies$ K.E = 8%

$\therefore$ Percentage error in kinetic energy is 8%.
