If a pronghorn antelope accelerates from rest in a straight line with a constant acceleration of 1.5 m/s2 , how long does it take for the antelope to reach a speed of 18 m/s?

• physics -

V = Vi + a t
18 = 0 + 1.5 t

• high school -

it takes the pronghorn antelope 12 seconds to reach 18 meters a second
