A net force acting on a 5.0 kg box produces an acceleration of 4.2 m/s2. What

liq [111]

Answer:

14 N

Step-by-step explanation:

Let the mass of the box be m.

F = ma → F = 5 x 4.2 = 21 N

When mass = 2.8 kg, let the acceleration is a. For same force:

=> 21 = a x 2.8

=> 21/2.8 = a

=> 7.5 m/s² = a

Graph f(x) = 3 sin (1/2x) - 5<br><br> Use 3.14 for (pi sign) <br><br> (idk where to graph is at)

timurjin [86]

Answer:

The graph of the function is attached in the figure a.

Step-by-step explanation:

Considering the expression

$f\left(x\right)=3\sin \left(\frac{1}{2}x\right)-5$

As we have to determine the graph of the function

$f\left(x\right)=3\sin \left(\frac{1}{2}x\right)-5$
Using 3.14 for pi

The graph of the function is attached in the figure a.

Please check the attached figure a to visualize the graph.

Hope if helps.
