What engine thrust is required for a rocket of mass 35 kg to leave the launching pad? 3.5 N. 35 N. 351 N. 3,500 N. 35,000 N.

soldi70 [24.7K]

In order for the object to move upward, it needs an upward force
that's at least equal to its own weight.

Weight = (mass) x (gravity) = (35 kg) x (9.8 m/s²) = 343 N.

The engine thrust has to be more than 343 N.

The displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s

Veseljchak [2.6K]

Answer:

$v_{avg} = 0$

Explanation:

The object is moving to and fro about its mean position

and the equation for its displacement is given as

$s = 5 sin(\pi t) + 5 cos(\pi t)$

now in one complete time period we know that the the object will complete its one oscillation

So the change in the position of the object in one complete time period will be ZERO

so here we can say that

$v_{avg} = \frac{displacement}{time}$

since change in position is zero

so displacement = 0

$v_{avg} = 0$

The force on the truck is F=13650 N

<u>Explanation:</u>

Solving the problem

Given data,

M= 1500 kg

A= 9.1 m/s

We have the formula,

F= M×A

F= 1500 × 9.1

F=13650 N

The Force on the truck is F=13650 N

Each planet orbiting our sun is unique. Yet the four inner planets have much in common. Mercury, Venus, Earth and Mars are terrestrial or telluric planets. They are rocky with a dense metal core consisting mostly of iron. Planetary scientists theorize that Mars and Venus may once have had conditions like Earth's, favorable to life. The name "terrestrial" comes from the Latin word "terra," which means land. There are at least four Jovian or gas planets in our solar system. Jovian planets such as Jupiter, Saturn, Uranus and Neptune are large planets that are composed of light materials such as hydrogen and helium. The name "Jovian" comes from the planets' resemblance to Jupiter. The moniker "gas planet" is slightly misleading, since the interior of these frigid planets is gas supercooled to a liquid state.
