Question

What does it mean to have an acceleration of -10 m/s^2 when the velocity is 80 m/s?

Select all correct answers...
1. The object is slowing down.
2. The object is speeding up.
3.The object will stop in 8 seconds.
4. A negative acceleration is not possible.
5. The object is at rest.

Answer 1

1,3

Step-by-step explanation:

As the acceleration is -10m/s^2 , that means deceleration is occurring. That means, the object is slowing down.

v=u-at

or, 0=80-10t

or, t=8 seconds

So, the object will stop in 8 seconds.

So, the correct answers are 1 and 3.

Hope, this helps you.
