What was his average acceleration?

What velocity did he acheive when he caught the ball?

Thank you!

Please post your work.

For velocity I have 3.333 meters/second.

I was not sure how to find acceleration, or what formula to use.

My teacher gave us this formula: velocity = velocity(sub zero) + at . So should I make a permuatation out of this formula to give me: a = (velocity - velocity(sub zero)) / t ?

So then a = 3.333m/s - (initial velocity) / time

I'm pretty confused. Thanks for helping.

You have these formulas

x=v

v=v

v

Which equation has acceleration, time and distance in it?

For example:

Vinitial=0 m/s t=3s d=10m a=? Vfinal=?

These formulas should help.

d= 1/2 (Vi+Vf)t

Vf= Vi + at

d=Vi(t) + 1/2 a(t^2)

G'luck!
