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>16 m/s2</p>
c
<p>10. m/s2</p>
d
<p>0.25 m/s2</p>
The acceleration of the object can be calculated using the formula:
acceleration = (final velocity - initial velocity) / time
We are given that the final velocity is 8.0 m/s, the initial velocity is 0 m/s, and the time is 2.0 seconds. Plugging in these values, we get:
acceleration = (8.0 m/s - 0 m/s) / 2.0 s
acceleration = 8.0 m/s / 2.0 s
acceleration = 4.0 m/s^2
Therefore, the acceleration of the object is 4.0 m/s^2.
Answer: a) 4.0 m/s^2
