An object originally at rest is uniformly accelerated to a speed of 8.0 meters per second in 2.0 seconds. What is the acceleration of the object?
\large acceleration=\frac{v_{final}-v_{initial}}{time}
a
<p>4.0 m/s2</p>
b
<p>0.25 m/s2</p>
c
<p>16 m/s2</p>
d
<p>10. m/s2</p>
To find the acceleration of the object, we can use the formula:
\[acceleration = \frac{v_{final} - v_{initial}}{time}\]
Given that the initial velocity (\(v_{initial}\)) is 0 m/s, the final velocity (\(v_{final}\)) is 8 m/s, and the time (\(time\)) is 2 seconds, we can substitute these values into the formula:
\[acceleration = \frac{8 \, \text{m/s} - 0 \, \text{m/s}}{2 \, \text{s}}\]
Simplifying this expression, we get:
\[acceleration = \frac{8 \, \text{m/s}}{2 \, \text{s}} = 4 \, \text{m/s}^2\]
Therefore, the acceleration of the object is 4.0 m/s^2.
So, the correct option is a) 4.0 m/s^2.
