Question

a zebra starts from rest and accelerates at 1.9m/s. how far has the zebra gone after 5 seconds

Answer 1

the correct units for acceleration in m/s^2

the equation you need for this applies to constant acceleration:

s=ut + 0.5 at ^2

s is distance
u is initial velocity (start from rest means u=0)
a = 1.9m/s^2
t = 5

so plug those numbers into the equation, and solve for s
