To find the velocity after 5 seconds, we can use the equation for constant acceleration:

'v = u + at'

Where:

  • v = final velocity
  • u = initial velocity (which is 0 m/s since you start from rest)
  • a = acceleration (-2 m/s/s)
  • t = time (5 seconds)

Plugging the given values into the equation, we have:

v = 0 + (-2)(5) v = 0 - 10 v = -10 m/s

Therefore, your velocity after 5 seconds is -10 m/s.
