A train traveling at 10 m/s accelerated at a rate of
3 m/s2 for 6 seconds. What is the speed at the
end of 6 seconds?

Respuesta :

Answer:  28 m/s

Work Shown:

  • Vi = starting or initial velocity = 10 m/s
  • Vf = unknown final velocity
  • a = acceleration = 3 m/s^2
  • t = duration of time = 6 seconds

Use those values in the following kinematic equation

Vf = Vi + a*t

Vf = 10 + 3*6

Vf = 10 + 18

Vf = 28

The final velocity is 28 m/s
