Question

A particle is moving up an inclined plane. Its velocity changes from 15m/s to 10m/s in two

seconds. What is its acceleration?

Answer 1

Step-by-step explanation:

We can use the formula for acceleration:

acceleration = (final velocity - initial velocity) / time

Plugging in the values given in the problem, we get:

acceleration = (10 m/s - 15 m/s) / 2 s

Simplifying this expression, we get:

acceleration = -5 m/s / 2 s

Therefore, the acceleration of the particle is -2.5 m/s^2.

Note that the negative sign indicates that the particle is decelerating or slowing down.
