1. The problem statement, all variables and given/known data 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. 2. Relevant equations v=u+at 3. The attempt at a solution 8ms-1 = 0 + at but time is what time between footprints is only known time?
