Third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices.

A 0.68 kg squirrel is resting on a branch 8 meters above the ground. What is the gravitational potential energy of a squirrel? A
ANEK [815]

Answer:

The gravitational potential energy of a squirrel is 53.312 J.

Explanation:

We have,

Mass of a squirrel is 0.68 kg

It is placed at a height of 8 m above the ground.

It is required to find the gravitational potential energy of a squirrel. It is possessed by an object due to its position. Its formula is given by :

E=mgh\\\\E=0.68\times 9.8\times 8\\\\E=53.312\ J

So, the gravitational potential energy of a squirrel is 53.312 J.

The Earth orbits the sun with a speed of about 67000 miles per hour. If the Earth was to suddenly stop, it would
kozerog [31]

Answer: It would destroy the Earth's surface.

I remember reading this questions in What If? by Randall Munroe. Great book, I suggest you check it out. Anyway, the answer. The Earth is revolving as well as spinning on its axis at the same time. This  basically means that thee atmosphere is also spinning at the same speed. But due to the frame of reference, we don't notice anything. If the Earth suddenly stops spinning, then the atmosphere, going according to the first law of motion will still be spinning at the same speed. This would produce supersonic winds at such a scale that it will be compared to an atomic explosion. Anything not in a nuclear bunker will probably be ripped apart by the force of the wind.

1. If a model train car with a momentum of 12 kg•m/s collides with a 2 kg model train car that is not moving, what is the total
wariber [46]

Answer:

P_{f} = 12 \ kg.m/s

Explanation:

Given data:

Momentum of moving model train, P_{1} = 12 \ kg.m/s

Mass of the stationary model train, m = 2 \ kg

Initial speed of the stationary model train, v = 0

Assume there is no external force is acting on the given train system.

In this case, the total linear momentum of the trains would be conserved.

Let the final linear momentum of the trains be P_{f}.

Thus,

P_{i} = P_{f}

P_{1} + P_{2} = P_{f}

P_{1} + mv = P_{f}

12 + 2 \times 0 = P_{f}

\Rightarrow \ P_{f} = 12 \ kg.m/s.
