Answer:
acceleration = - 10.952
Explanation:
Since it was traveling at 74m/s initially, initial velocity - 74m/s.
Second, since it came to a stop, final velocity - 0 m/s.
Displacement - 250 m.
Use the kinematic equation to solve for acceleration.
[tex]v_f^2 = v_i^2 + 2ax[/tex]
0^2 = 74^2 + 2(a)(250)
0 = 5476 + 500a
-5476 = 500a
a = -5476 / 500 = -10.952
