Question

What is the acceleration of a car that starts from rest and is moving at 50 mph after 4 seconds? *
Your answer should be in mi/h/s (miles per hour, per second)

Answer 1

Answer:

a=v−u2

where v is final velocity and u is initial velocity.

so (50−0)/5=10m/s2

d=vt+at22

v=0

a=10

t=5

therefore

d=0+0.5⋅10⋅52=125 meters
