1. The problem statement, all variables and given/known data
An antelope moving with constant acceleration covers the distance 74.0m between two points in time 7.70s . Its speed as it passes the second point is 14.6 m/s. 2. Relevant equations What is its speed at the first point? What is the acceleration? 3. The attempt at a solution I dont know how to type in the formula in here any help? Im kinda confused on how to substitue the formula.

Hi c0ld
To type formula here, we use Latex. I don't know if there is a thread somewhere here about Latex tutorial, maybe you can use google. About your question, the formulas for kinematics : [tex]1) v = u+at[/tex] [tex]2) s=ut+\frac{1}{2}at^2[/tex] [tex]3) v^2=u^2+2as[/tex] v = final speed u = initial speed Apply those formulas and you'll find the answer

What does s mean? Displacement?
First point should be initial velocity. All the formulas you posted require acceleration.

Initial Velocity without acceleration given.
Got the problem! It was ((2 * Displacement) / t)  final velocity
