A ball is thrown vertically upward, which is the positive direction. A little while later it returns to its point of release. Th
valkas [14]

Answer:

v_0=\frac{y}{t}-\frac{at}{2}

v_0=49m/s

Explanation:

We can start from the known formula:

y=y_f-y_0=v_0t+\frac{at^2}{2}

so we can write, since we want the initial velocity in terms of the ball's displacement, its acceleration in the vertical direction, and the elapsed time:

v_0=\frac{y}{t}-\frac{at}{2}

and for our values we have:

v_0=\frac{0m}{10s}-\frac{(-9.8m/s^2)(10s)}{2}=49m/s
