A toy car of mass 5 kg moves up a ramp under the influence of force F plotted against displacement x. The maximum height attained is given by

A

`y_("max") = 20m `

B

`y_("max") = 15m `

C

`y_("max") = 11m `

D

`y_("max") = 5m `

Text Solution

Verified by Experts

The correct Answer is:
C
`W =1/2 xx 11 xx100 = 550 J`
Now, conservation of energy –
W = mgh
`implies 550 = 5 xx10 xx h implies h = 11 m`
