What is the magnitude of velocity for a 2,000 kg car possessing 3,000 kg(*)m/s of momentum?
Trava [24]

The magnitude of velocity for this car is equal to 1.5 m/s.

<u>Given the following data:</u>

  • Momentum of car = 3,000 kgm/s.
  • Mass of car = 2,000 kg.

To calculate the magnitude of velocity for this car:

<h3>What is momentum?</h3>

In Science, momentum simply means a multiplication of the mass of an object and its velocity.

Mathematically, momentum is giving by the formula;

Momentum = mass \times velocity

Making velocity the subject of formula, we have:

Velocity=\frac{Momentum}{Mass}

Substituting the given parameters into the formula, we have;

Velocity=\frac{3000}{2000}

Velocity = 1.5 m/s.

A very small tilt in Earth’s axis would likely cause ____.
olchik [2.2K]
If the Earth's axis were closer to "straight up and down" than
the present 23.5°, then . . .

-- The areas around the north and south poles where the sun
can be up or down for more than 24 hours would be smaller.

-- The "Tropic Zone", between the Tropic of Cancer and the
Tropic of Capricorn, where it's possible for the sun to be
directly overhead, would be narrower.

-- There would be less difference, everywhere, between the
lengths of daylight on the "longest day" and the "shortest day"
of the year.

-- The seasons would be less extreme everywhere.  There would
be less difference, everywhere, between the coldest part of the
Winter and the warmest part of the Summer.
