Answer is " A convex line runs downward from 0 seconds some positive number of meters to some positive number of seconds 0 meters. "

Explanation:

The figure shows Velocity vs Time Graph.

At t1=0, u=10m/s

At t2=5, v=2m/s

Let's calculated the acceleration

$a=\frac{v-u}{t2-t1}$

$a=\frac{2-10}{5-0}$

$a=\frac{-8}{5}$

The equation of distance is given by

$d=ut+\frac{a}{2} t^{2}$

$d=(10)t+\frac{\frac{-8}{5}}{2} t^{2}$

$d=10t+\frac{-8}{10} t^{2}$

$d=10t+\frac{-4}{5} t^{2}$

$5d=50t-4t^{2}$

From here, You can plot the graph of above equation by taking several points.

When t=0,

$5d=50(0)-4(0)^{2} = 0m$

When t=5,

$5d=50(5)-4(5)^{2}$

5d=250-100

5d=150

d=30m

Similarly,

When t= 3s d=22.8m

When t=4s d=27.2m

Figure shown is graph of Distance vs Time.

Thus, answer is " A convex line runs downward from 0 seconds some positive number of meters to some positive number of seconds 0 meters. "

Iwould choose the same momentum because if they throw a baseball very light and not hard at all then doing it with a bowling ball won’t hurt that worse
