Question

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

Answer 1

-2.5 m/s2.............................

Answer 2

Answer:

Explanation:

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
