A car is traveling with a speed of 24 m/s.What is the magnitude of the acceleration necessary to stop the car in a distance of 60 m? A)0.4 m/s² B)2.5 m/s² C)4.8 m/s² D)6.1 m/s² E)9.6 m/s²

Question

The formula for acceleration is:

a = (vf^2 - vi^2)/ 2d

where,

vf = final velocity (0 m/s)
vi = initial velocity (24 m/s)
d = distance (60 m)

Substituting the given values, we get:

a = (0^2 - 24^2)/2(-60)
  = 576/120
  = 4.8 m/s^2

Therefore, the magnitude of the acceleration necessary to stop the car in a distance of 60 m is 4.8 m/s^2. The correct answer is C.

A Car Is Traveling with a Speed of 24 M/s
