Answer:
B. 17m/s
Explanation:
This question contains a graph that illustrates the relationship between the speed of a car over time. The graph shows that one can make an inference of the amount of time it takes for the car to cover a particular speed and vice versa.
In this case, after 3 seconds, the speed of the car will be 17 m/s. This inference was got by tracing the position of 3s in the x-axis to the value on the y-axis. Doing this, the best inference for the speed of the car after 3 seconds is 17m/s.
Answer:
It is Potassium and iodine
<span>F = ma
</span>Ff = μ*Fn
<span>Fn = Fw
</span>Fw = mg
<span>So we have: </span>
<span>Ff = μmg </span>
<span>And </span>
<span>Ff = ma </span>
<span>So... </span>
<span>μmg = ma </span><span> </span>
<span>μg = a </span>
<span>And we can solve for the acceleration: </span>
<span>(0.15)(9.81 m/s²) = a </span>
<span>a = 1.47 m/s² </span>
