Question

if your car starts from rest and has an acceleration of 3.2 m/s2 how fast are you going after you have driven 20m

Answer 1

Answer:8√(2) m/s

Step-by-step explanation:

Initial velocity(u)=0

Acceleration(a)=3.2m/s^2

Distance(d)=20m

Final velocity(v)

v^2=u^2+2xaxd

v^2=0^2+2 x 3.2 x 20

v^2=128

Take them square root of both sides

v=√(128)

v=8√(2) m/s
