Answer:

<h2>4m /s.</h2>

Explanation:

Acceleration is defined as the change of velocity, that is, when the velocity increases or decreases, there's acceleration. When the velocity doesn't change, there's no acceleration or it's null.

So, in this case, the initial velocity of the accelerated period is 4m/s, and after the period is 60m/s. This means 4m/s represents the velocity before the acceleration and 60m/s represents the velocity after the acceleration.

Therefore, the right answer here is 4m/s.

Well it seems like this problem gives you what you need.  You said the car was going 4m/s and then accelerated to 60m/s... so 4m/s would be your answer for the initial velocity

1. write the meaning of the following terms:electrostatic,neutral, positively charged, negatively charged, coulomb,microcoulomb,
dybincka [34]

ELECTROSTATIC:

relating to stationary electric charges or fields as opposed to electric currents.

NEUTRAL:

nor negative nor positive/having no charge

POSITIVELY CHARGED:

positive charge occurs when the number of protons exceeds the number of electrons

NEGATIVELY CHARGED:

negative charge occurs when the number of electrons exceeds the number of protons.

COULOMB:

SI unit for electric charge. One coulomb is equal to the amount of charge from a current of one ampere flowing for one second.

MICROCOULOMB:

a unit of electrical charge equal to one millionth of a coulomb.

NANOCOULOMB:

Nanocoulombs are a unit of charge 1,000,000,000 times smaller than Coulomb.

CONSERVATION OF CHARGE:

constancy of the total electric charge in the universe or in any specific chemical or nuclear reaction

QUANTISATION OF CHARGE:

Charge quantization is the principle that the charge of any object is an integer multiple of the elementary charge.

Can I get help and an explanation on C?
Diano4ka-milaya [45]

Answer:

1.67 m/s

Explanation:

Momentum is conserved.

Initial momentum = final momentum

(30 kg) (10 m/s) + (35 kg) (-10 m/s) = (30 kg) v + (35 kg) (0 m/s)

300 - 350 = 30v

v = -5/3 m/s

Linus will move at 1.67 m/s in the direction opposite that he started.

Find the initial velocity of a car which stops in 10sec, after applying brakes at the rate of 2m/s²
Dennis_Churaev [7]

Answer:

20\ m/s

Explanation:

Since we are given time, acceleration, and final velocity, we can use the following formula to find the initial velocity:

v_f = v_i + at

Our given values:

v_f = 0\\a = -2\\t = 10\\

<em>Acceleration is negative because the car is slowing down.</em>

Add the values to the formula, and solve for v_i:

v_f = v_i + at\\0 = v_i + (-2)(10)\\0 = v_i -20\\20 = v_i
