Using the formula for acceleration:
acceleration = (vfinal - vinitial)/time
Given:
vinitial = 0 m/s
vfinal = 8.0 m/s
time = 2.0 s
Substituting the given values into the formula:
acceleration = (8.0 - 0) / 2.0
acceleration = 8.0 / 2.0
acceleration = 4.0 m/s^2
Therefore, the acceleration of the object is 4.0 m/s^2.
The correct answer is b) 4.0 m/s^2.
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>0.25 m/s2</p>
b
<p>4.0 m/s2</p>
c
<p>16 m/s2</p>
d
<p>10. m/s2</p>
