How to find weight in science

1 answer:

8 0

There are several different methods, depending on the particular situation. A few that might occasionally be useful include:

-- Read the label on the package.

-- Measure the mass and multiply by the local acceleration of gravity.

-- Measure the mass AND the local acceleration of gravity, then multiply.

-- Place the object or sample on a bathroom scale.

-- Place the object on one end of a symmetrical see-saw. Through trial and error, determine the weight required on the other end to balance the system.

A 92kg astronaut and a 1200kg satellite are at rest relative to the space shuttle. The astronaut pushes on the satellite, giving

Harman [31]

Answer:

13.7m

Explanation:

Since there's no external force acting on the astronaut or the satellite, the momentum must be conserved before and after the push. Since both are at rest before, momentum is 0.

After the push

$m_av_a + m_sv_s = 0$

Where $m_a = 92kg$ is the mass of the astronaut, $m_s = 1200kg$ is the mass of the satellite, $v_s = 0.14 m/s$ is the speed of the satellite. We can calculate the speed $v_a$ of the astronaut:

$v_a = \frac{-m_sv_s}{m_a} = \frac{-1200*0.14}{92} = -1.83 m/s$

So the astronaut has a opposite direction with the satellite motion, which is further away from the shuttle. Since it takes 7.5 s for the astronaut to make contact with the shuttle, the distance would be

d = vt = 1.83 * 7.5 = 13.7 m
