An object with acceleration of -10 m/s2 is.....
a. speeding up 10 m/s every second
b.slowing down 10 m/s every second
c.moving a constant speed of -10 m/s
d.moving at a constant velocity of -10 m/s
((I think the answer is C but I second guess myself a lot. So I'm not sure.))
NO !!!!
it is accelerating in direction opposite to x axis, probably slowing down.
so: B
To determine the correct answer, let's break down the information given. An acceleration of -10 m/s^2 means that the object is experiencing a negative acceleration. Acceleration is the rate of change of velocity.
If the acceleration is negative (in this case, -10 m/s^2), it means the object's velocity is decreasing over time. In other words, the object is slowing down.
Based on this information, the correct answer is b. The object is slowing down at a rate of 10 m/s every second.
To better understand this concept, you can use the following formula:
Acceleration = (Change in velocity) / (Change in time)
Rearranging this formula, we have:
Change in velocity = Acceleration × Change in time
In this case, the acceleration is -10 m/s^2 and the change in time is 1 second. So:
Change in velocity = -10 m/s^2 * 1 second = -10 m/s
Note that the negative sign indicates a decrease in velocity. Therefore, the object is slowing down by 10 m/s every second.
