How to find final velocity and initial velocity and acceleration ? :(

Physics
1 answer:
Effectus [21]3 years ago
3 0

Explanation:

Final velocity=Initial velocity+(acceleration×time)

4 ways to find initial velocity:

1) Initial velocity=Final velocity-(acceleration×time)

2) Initial velocity=(Distance/Time)-((acceleration×time)/2)

3) Initial velocity=√Final velocity-(2×(acceleration×distance))

4) Initial velocity=2(distance/time)-Final velocity

Total force = Mass×Acceleration

(F=ma)

13. A transformer has a primary coil with 600 turns and a secondary coil with 300 turns. If the output voltage is 320 volts, wha
vivado [14]
His is a step down transformer since n(primary) is greater than n(seconcary). You relate the input voltage with the ouput voltage with the following equation: 

<span>Vout = n2/n1*Vin (n2/n1 is essentially your 'transfer function' that dictates what a specified input would produce) </span>

<span>Solving the equation: </span>

<span>Vin = Vout*n1/n2 = (320V)*(600/300) = 640 V </span>

<span>This is checked by seeing if Vin is greater than Vout, which it is for a step down transformer.</span>

∠1 and ∠2 are vertical angles. If m∠1 = (17x + 1)° and m∠2 = (20x – 14)°, find m∠2. Answer with "m∠2=_"
Bingel [31]

Answer:

m<2 = 86

Explanation:

Vertical angles means the angles are equal to each other so:

<1 = <2

17x + 1 = 20x - 14

17x - 20x = -14 - 1

-3x = -15

x = 5

m<2:

20x - 14

20(5) - 14

100 - 14

86
