Answer:

6.0 m/s^2           There are 2 places of accuracy. (5.0 has only two places)

Explanation:

Formula

This uses the formula

a = (vf - vi)/t where

  • a is the acceleration
  • vf is the final speed
  • vi is the starting speed.
  • t is the time taken

Solution

Substitute the givens into the formula

a = (50m/s - 20 m/s)/5

a = 30/5

a = 6 m/s^2
