Question Number 116355 by Rio Michael last updated on 03/Oct/20
the speed v of a projectile launched at  an angle α to the horizontal is thought to  be given by :         v = [(1/k)(A + ((sin αt)/g)) + e^(−C/t) ]  where k,A,  α and C are constants, t is time  and g is the gravitational acceleration.  determine the base units of A, α and C
