Question

9. An object is moving up an inclined plane. Its velocity changes from 15m/s to 10m/s intwo seconds. What is its acceleration?

​

Answer 1

Initial velocity of object (u) = 15m/s

Final velocity of object (v) = 10 m/s

Time taken (t) = 2 seconds

As, we know formula for acceleration is -

(v-u)/t

So, Acceleration = (10-15)/2

= -5/2

= -2.5 m/s²

Answer : Acceleration of body is -2.5 m/s²

mark as brainlest answer please

Answer 2

Answer:

Explanation:

given,

initial velocity, u= 15m/s

final velocity, v= 10m/s

time, t= 2s

acceleration, a= ?

now,

a= (v-u)/t

a= (10-15)/2

a= -5/2

a= -2.5m/s^2

hope it helps...thank you
