A lead ball moving with velocity v strikes a wall and stops. iF 50% of its energy is converted into heat, then what will be the increase in temperature ? Specific heat of lead is s

A

`(2v^(2))/(J s) `

B

`(v^(2))/(4 Js)`

C

`(v^(2)s)/(J)`

D

`(v^(2)s)/(2J)`

Text Solution

Verified by Experts

The correct Answer is:
B
`(1//2)mv^(2) xx (50//100) =J xx H = J xx ms DeltaT`
`DeltaT = v^(2)4JS`.
