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 J

B

`10^(-2) J`

C

`8 xx 10^(-2) J`

D

`4 xx 10^(-2) J`

Text Solution

Verified by Experts

The correct Answer is:
C
Work done = m `xx` (area under the graph)
`=10xx(1)/(2)xx20xx8xx10_(-4)J=8xx10_(-2)J`
