What is an object's acceleration if it is moving at 30 m/s and comes to a stop in 5 s? - 30 m/s2 - 6 m/s2 30 m/s2 6 m/s2

The acceleration is - 6 m/s2

Explanation:

The equation for the speed of a body is

V = Vo + a t

Where

Vo is the initial velocity, a is the acceleration and t is the time,

When the body stops the speed is zero

0 = Vo + a t

a = Vo / t

substitute values

a = - 30/5

a = - 6 m/s2

The negative sign indicates that acceleration opposite movement

Answer:32m/s
