Newton’s Third Law!

Every action has an equal, but opposite, reaction. When you jump from the boat, you exert force on the boat as you leap from it. Since the boat rests on a liquid instead of a solid (much less friction), it moves away from the jumper as a result of the leap.

A student drops a ball off the top of building and records that the ball takes 3.82s to reach the ground. Determine all unknowns

klemol [59]

Explanation:

Given parameters:

Time of drop = 3.82s

Unknown:

Final velocity of the ball = ?

Height of fall = ?

Solution:

To solve this problem, we apply the appropriate motion equation.

To find the final velocity;

v = u + gt

v is the unknown final velocity

u is the initial velocity = 0m/s

g is the acceleration due to gravity = 9.8m/s²

t is the time

v = 0 + 9.8 x 3.82 = 37.4m/s

Height of drop;

H = ut + $\frac{1}{2}$ gt²

So;

H = (0 x 3.82) + ( $\frac{1}{2}$ x 9.8 x 3.82²) = 71.5m

In the combo circuit diagrammed, R1 = 19.2 Ω, R2 = 20.7 Ω, and R3 = 25.8 Ω. Find the equivalent resistance of the circuit.

garik1379 [7]

Answer:

Equivalent resistance: 13.589 Ω

Explanation:

R series = R1 + R2 + R3 ...

$\frac{1}{R_{eq} } = \frac{1}{R1} +\frac{1}{R2} +\frac{1}{R3} ...$

Find the equivalent resistance of the right branch of the circuit:

$R_{eq} = R_{2} +R_{3} \\R_{eq} = 20.7 + 25.8 = 46.5 ohms$

$\frac{1}{R_{eq} } = \frac{1}{19.2} +\frac{1}{46.5}\\\\\frac{1}{R_{eq} } = 0.0735887097\\\\R_{eq} = 13.5890411$

Explanation:

For this exercise we will take the condition of rotational equilibrium, where the reference system is located on the far left and the wire on the far right. We assume that counterclockwise turns are positive.

Let's use trigonometry to decompose the tension

sin 60 = $T_{y}$ / T
