What happens in terms of energy when a moving car hits a parked car, causing the parked car to move?

Answers

ANSWER:

The moving car transfers kinetic energy to the parked car.

EXPLANATION:

Kinetic energy is the energy an object has because of its motion and can be transferred between objects and transformed into other kinds of energy.

When a moving car hits a parked car, causing the parked car to move, the type of collision is elastic collision. An elastic collision is when two bodies collide and separates after collision conserving the total kinetic energy before and after collision.

A 3.7 kg object is lifted to a Hight of 3 meters what is the potential energy of this object

Answers

Gravitational potential energy = (mass) x (gravity) x (height)

PE = (3.7) x (9.81) x (3)
= 108.89 kilogram-meters²/second
= 108.89 newton-meters
= 108.89 joules

The acceleration due to gravity on Jupiter is greater than that on Earth. On Jupiter, a person will weigh .

Answers

The acceleration due to gravity on Jupiter is 24.79 m/s²,
compared to 9.8 m/s² on Earth ... a ratio of about 2.53 .

So if a person or object were somehow transported to Jupiter,
he/it would weigh

           (2.53) times (Earth weight)

What is the momentum of a 52 kg carton that slides at 5.0m/s across an icy surface?

Answers

Formula for momentum is mass times velocity so you do 52 kg times 5 m/s and that equals 260 kg x m/s

If 1.3 grams of air has a volume of 1000cm ^3, what is the density of air? A) 1300g/cm^3
B) 1001.3 g/cm^3
C) 769.23 g/cm^3
D) 0.0013 g/cm^3

Answers

Answer:

Density, d=0.0013\ g/cm^3

Explanation:

Given that,

Mass of the air, m = 1.3 grams

Volume of the air, V=1000\ cm^3

The density of the air is given by total mass divided by total volume. Mathematically, it is given by :

d=(m)/(V)

d=(1.3\ g)/(1000\ cm^3)

d=0.0013\ g/cm^3

Hence, this is the required solution.

D)
Density is equal to mass/volume, so in your case:
density=1.3/1000=0.0013 g/cm^3

A car with a mass of 1500 kg is traveling at a speed of 30 m/s. Calculate its kinetic energy.step by step pls​​

Answers

Explanation:

KE = 1/2 mv²,

where KE is the kinetic energy,

m is the mass,

and v is the velocity.

Given m = 1500 kg and v = 30 m/s:

KE = 1/2 (1500 kg) (30 m/s)²

KE = 675,000 J

KE = 675 kJ
