The velocity function of an object moving along a straight line is given by `v(t)=At^(2)+Bt`. If at t=2s, the velocity is 3 m/s and acceleration is `0
The velocity function of an object moving along a straight line is given by `v(t)=At^(2)+Bt`. If at t=2s, the velocity is 3 m/s and acceleration is `0.500 m//s^(2)`, find the value of the constant A.
A. `-0.5m//s^(3)`
B. `-0.5 m//s^(2)`
C. `-2.5m//s^(3)`
