Question

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>10. m/s²</p>
b
<p>16 m/s²</p>
c
<p>0.25 m/s²</p>
d
<p>4.0 m/s²</p>

Answer 1

To find the acceleration of the object, we can use the formula:

acceleration = (final velocity - initial velocity) / time

In this case, the initial velocity is 0 m/s (since the object is originally at rest), the final velocity is 8.0 m/s, and the time is 2.0 s.

Plugging these values into the formula, 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: d) 4.0 m/s^2
