Ipatiy [6.2K]

Answer:

86.6 lbs

Explanation:

Let the force is X.

Resultant force, R = 100 lbs

Other force is Y. Angle between resultant force and force X is 30°.

According to the diagram

Cos30=\frac{X}{R}

0.866=\frac{X}{100}

X = 86.6 lbs

Other force Y

Sin30=\frac{X}{R}

0.5=\frac{Y}{100}

Y = 50 lbs

Andru [333]

Explanation :

It is given that, a heavy box is in the back of a truck and the truck is accelerating to the right.

The description is shown in<em> figure 1</em>. Here, the forces that act on both box and the truck are the normal force, the frictional force and their weight mg.

The free body diagram is shown in <em>figure 2</em>. This shows the total forces            ( F = ma )acting on the truck. As a result, the truck will move in a forward direction.

Hence, this is the required explanation.

PLEASE PLEASE HELP!!!!!! thank you soo much!!! *will give brainliest*
stiks02 [169]

Answer:

F=1.13\,*\,10^{15} (answer a)

Explanation:

Recall the formula for the Coulomb force:

F=k\frac{q_1*q_2}{d^2}

which in our case gives:

F=k\frac{q_1*q_2}{d^2} \\F=9*10^9\,\frac{63*45}{0.15^2} \\F\approx 1134000\,*\,10^9\\F\approx 1.13\,*\,10^{15}

which agrees with answer a)
