Question

a lorry is travelling with a velocity of 100 m/s came to rest in 25 seconds what is its acceleration​

Answer 1

Answer:

Velocity = 100 m/s

Time = 25 second

Acceleration = ?

According to the questions

Acceleration = Change in velocity / Time Taken

Acceleration = v - u/ t

= 100m/s - 0 / 25t

= 4 m/s^2.

Answer 2

Answer:

acceleration is -4m/s^2

Explanation:

acceleration= final velocity - initial velocity/ total time taken

then acceleration= 0-100/25

-4m/s^2
