the mathematical relationship between velocity (v) and time (t) for a coin tossed up into the air after it leaves the thrower¡¦s hand at t = 0 with a velocity of +15.0 m/s. Assume that the positive direction is upward and the acceleration of the coin is ƒ{9.8 m/s2.

What is the question?
v(t)=15m/s  9.8m/s^2 * t 
Write down the mathematical relationship between velocity (v) and time (t) for a coin tossed up into the air after it leaves the thrower¡¦s hand at t = 0 with a velocity of +15.0 m/s. Assume that the positive direction is upward and the acceleration of the coin is ƒ{9.8 m/s2.

so I did it, right?

i think

so is my answer 0 for this?
