A 10 kg mass moves x-axis. Its acceleration as function of its position is shown in the figure. What is the total work done on the mass by the force as the mass moves from x = 0 to x = 8 cm ?

A

`8 xx 10^(-2)` joules

B

`16 xx 10^(-2)` joules

C

`4 xx 10^(-4)` joules

D

`1.6 xx 10^(-3)` joules

Text Solution

Verified by Experts

The correct Answer is:
A
`W =M xx` (area under a - S graph)
`=10 xx1/2 xx 8 xx 20 xx10^(-4) = 8 xx10^(-2) J`
