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.
