Physics Test Question Solution?

[MyNameIsMud]

Homework Statement

So I just had a Physics test and I couldn't get the solution to this problem. I was hoping someone could tell me how to do it correctly.

This isn't the exact wording, as I already forgot it, but here it goes:

A skateboarder moves on his skateboard horizontally 3.2m, in that distance his velocity changed from 95 cm/s to 51 cm/s. what is the acceleration assuming its constant? What is the total time of this event?

Homework Equations

5 equations for constant acceleration

The Attempt at a Solution

It's on my test paper.

Welcome to the PF.

What is the equation for acceleration in terms of Δv and Δt?

Be sure to be consistent in your units as well. It's probably best to convert those velocities into m/s before doing the calculation.

One of those kinematic equations relates the following:

initial velocity
final velocity
displacement
acceleration​

Use that equation.
