When the motorcyclist is at

`A`

, he increases his speed along the vertical circular path at the rate of

`v^(˙)=(0.04s)f(t)/(s^(2))`

where

`s`

is in ft . Take

`\rho =320ft`

. (Figure 1) Part A If he starts at

`v_(A)=2f(t)/(s)`

where

`s=0`

at

`A`

, determine the magnitude of his velocity when he reaches

`B`

. Express your answer to three significant figures and include the appropriate units.
