Hi Bob;
v=(vO)+at
vO is original velocity. It is zero.
v=at
Acceleration due to gravity 9.8 m/s2.
v=gt
v=(9.8 m/s2)(3.5 s)
The unit of seconds to the exponential of 1 is in the denominator and numerator. It cancels...
v=(9.8 m/s)(3.5)
The only units remaining are m/s. This is what we want...
v=34.3 m/s
