A speeding train slams on the brakes when it sees a car is on the tracks in front of it. It takes the train 25 seconds for it to go from an initial speed of 75 m/s to come to a complete stop. What is the train’s acceleration?

Answer:

Acceleration of the train is -3 m/s²

Explanation:

Since it stops,

final velocity (v) = 0 m/s

time (t) = 25 seconds

initial velocity(u) = 75 m/s

Now,

accelereation = (v-u)/t

or, a = (0-75)/25

or, a = -75/25

so, a = -3 m/s²
