Answer:

Main Asteroid Belt: The majority of known asteroids orbit within the asteroid belt between Mars and Jupiter, generally with not very elongated orbits. The belt is estimated to contain between 1.1 and 1.9 million asteroids larger than 1 kilometer (0.6 mile) in diameter, and millions of smaller ones.

3. Same questions as the previous problem, but for mass m just falling 3 meters in a vacuum: (a) How long does it take mass m to

sveticcg [70]

Answer:

a) 0.78 s

b) 58.86m/s'

c) Galileo's law of free fall

Explanation:

a) $x = v_{i}t + \frac{1}{2}at^{2} \\3 = 0*t+\frac{1}{2} *9.81*t^{2}\\t=\sqrt{\frac{6}{9.81} }$

b)At the bottom:

kinetic energy = potential energy

$\frac{1}{2}mv^{2} = mgh\\ v^{2} =2*9.81*3=58.86m/s$ downwards

c) Galileo's law of free fall says regardless of the masses, bodies in a vacuum will fall, on the earth, at the same acceleration

A person runs 15 kilometers in two hours what is his/her average speed

bazaltina [42]

Answer:

$\displaystyle V=7.5\ km/h$

Explanation:

<u>Average Speed </u>

If an object travels a distance d in a time t regardless of the direction, the average speed is the quotient of the distance over the time:

$\displaystyle V=\frac{d}{t}$

It's known a person runs d=15 kilometers in t=2 hours, thus his/her average speed is:

$\displaystyle V=\frac{15\ km}{2\ h}$

Calculating:

$\boxed{\displaystyle V=7.5\ km/h}$
