A car traveling at 4.0 m/s has a constant acceleration of 2.0 m/s2. after 3.0 seconds, the average velocity during the acceleration is

Respuesta :

v1=4m/s,    v2=velocity after 3 sec,     average velocity= (v1+v2)/2

v2=a*dt (a=2, dt=3) ==>   v2=2*3= 6m/s
                                         v1= 4 m/s

average velocity= (4+6)/2 = 10/2 = 5 m/s

The average velocity during the acceleration is 5 m/s.

What is acceleration?

Acceleration is defined as the rate change of velocity with time.

acceleration a = (Δv) / (Δt)

A car traveling at 4.0 m/s has a constant acceleration of 2.0 m/s² after 3.0 seconds, the final velocity will be

2 = v/ 3

v = 6.0 m/s

Average velocity = 4.0 + 6.0 /2

                          V= 10/2

                          V = 5 m/s

Thus, the average velocity during the acceleration is 5 m/s.
