A 1200 kg automobile is traveling at a velocity of 100 m/s is its energy potential or kinetic? How much energy does it possess?

Answers

Answer 1

Answer:

The energy possess is 6,000,000 J

The kinetic energy is a energy by which an object can move and potential energy is a stored energy which depends upon the relative position of various parts of the body.

Given:

The mass of automobile is $m=1200\:\rm kg$ .

The velocity of the automobile is $100\;\rm m/s$ .

How to calculate potential energy and kinetic energy?

Write the formula to calculate the potential energy of the body.

$P.E=mgh$

Since the automobile is on ground so the height $h$ will be 0.

$P.E=1200* 9.81* 0\nP.E=0$

Write the formula to calculate the kinetic energy.

$K.E=(1)/(2)mv^2$

Substitute the value.

$K.E=(1)/(2)* 1200* 100^2\nK.E= 6,000,000 J.$

Answer 2

Answer:

Answer:

6,000,000 J (6 million)

Explanation:

Refer to the equations for potential and kinetic energy.

$KE = (1)/(2)mv^(2)\nPE = mgh$

Because the automobile is on the ground (it does not give a height above the ground, therefore we can assume that it is on the ground), height = 0. If you plug in 0 for h in the potential energy equation, we get PE = 0 J.

Therefore, all of the energy is kinetic. Plug in the given information into the kinetic energy equation. M = 1200 kg and v = 100 m/s

$KE = (1)/(2)mv^(2) = (1)/(2)(1200)(100^(2)) = 6,000,000\ J$

To dry the brakes, drive slowly in __________ and apply light pressure on your brake pedal.

Answers

The answer is low gear. To dry the brakes of a vehicle, one must driv slowly in low gear and apply light pressure on the vehicle's brake pedal. Dry brakes are less expensive and are cheap when it needs replacement, yet under pressure they may cause more damage to the system than wet brakes, which are better in terms of emergency.

Which of the following substances is a mixture? a. Baking soda b. Gasoline c. Salt d. Sugar

Answers

Among the following substances, Gasoline is a mixture. The correct option is (b).

Octane, heptane, and other hydrocarbon molecules obtained from petroleum are all mixed together to make petrol. The gasoline utilized in engines is not a single, pure material but rather a mixture of several different compounds.

Baking soda (a), salt (c), and sugar (d) are pure ingredients as opposed to mixes. While sugar (sucrose) is a pure organic component, baking soda (sodium bicarbonate) and salt (sodium chloride) are substances with particular chemical compositions.

Hence, the correct option is (b).
