How Fast and Powerful Was the T Rex?

[happyapple]

Homework Statement

calculate speed and momentum of T REX. Time between footprints is 0.62s - there are 2 footprints in a 10m distance, speed is constant - I need to show that the maximum speed is about 8ms-1 - how to I go about doing this? Help I have no idea
Its mass is 7000kg.

Homework Equations

v=u+at

The Attempt at a Solution

8ms-1 = 0 + at but time is what time between footprints is only known time?

They tell you that the speed is constant. Knowing this, can you use the time given and the distances given to find v? What formulas for v apply when v is constant?
