Question

Imagine you crash land your spacecraft on an unknown planet. The planet looks similar to earth, but you are not sure. To give you a hint on whether you are on earth or not, you drop a ball of mass 76.5 g from the top your spaceship. The height of the spaceship is 60 ft. The ball takes 2.5 s to reach the ground. Determine if you are on earth. If your weight on earth is 180 lbf, what is your weight on this planet in N? Show your work and all unit conversions for full credit.

Answer #1

The answer is in the images. Page number is mentioned at right top.

Your spaceship lands on an unknown planet. To determine the
characteristics of this planet, you drop a 1.50 kg wrench from 7.00
m above the ground and measure that it hits the ground 0.811
slater. You also do enough surveying to determine that the
circumference of the planet is 6.24×104 km .
1.) What is the mass of the planet, in kilograms?
2.) Express the planet’s mass in terms of the earth’s mass.

You land on an alien planet. While in orbit, you see that the
radius is 4075 km. While on the surface, you drop a rock (from
rest) from a height of 1.50 m above the surface and you observe
that the rock takes 0.734 s to reach the ground.
What is the mass of the planet?
What is the average density of this planet? (Assume the planet
is spherical. The volume of a sphere is ￼ V = 4 3...

Imagine you are on a planet outside our solar system and you
observe that your weight is the same as on Earth. However, the
planet has a larger size than Earth. Which statement about the
escape speed on that planet is correct? The escape speed is smaller
than that on Earth. The escape speed is larger than that on Earth.
The escape speed is the same as on Earth. The escape speed is zero.
The escape speed is infinitely large.

In order to get full credit, you need to show all your
work.
A ball is launched from the top of a 60 m high building with an
initial speed v0 at an angle 40° above the
horizontal (close to the surface of Earth). Air resistance is
negligible during the motion of the ball.
On the coordinate system shown with origin on the ground, draw
the path of the ball, the initial velocity vector, and its vector
components. Then find...

There’s life on Zoopledorf! While on a routine patrol in your
spacecraft outside the planet, you and your colleague Captain Clark
(who is traveling in her own completely separate ship) encounter an
unknown spacecraft, presumably crewed by Zoopledorfians. Apparently
spotting you as well, the strange ship accelerates away, and you
take this as an opportunity to learn more about its technological
capabilities. Specifically, you measure the ship’s acceleration in
order to determine the force its engine can exert. Using your...

1a. You wake up one morning to find yourself in a strange room
with opaque walls, and no visible doors or windows. You decide to
do some experiments to find out more about your strange situation.
Your own body mass is 51.0 kg. You pick up an object and drop it
from rest, starting at a height of 1.01 meters above the floor, and
it hits the floor 0.136 seconds later. You can ignore air
resistance. Based on the outcome...

1a. You wake up one morning to find yourself in a strange room
with opaque walls, and no visible doors or windows. You decide to
do some experiments to find out more about your strange situation.
Your own body mass is 60.4 kg. You pick up an object and drop it
from rest, starting at a height of 1.64 meters above the floor, and
it hits the floor 0.289 seconds later. You can ignore air
resistance. Based on the outcome...

When you jump, you start by crouching down a bit, which
lowers your center of mass to a distance d ≈ 40 cm below
where it normally is. You then exert a downward contact force on
the ground equal to about 2.5 times your weight (mg); we
may assume that this force is constant while it acts. After your
center of mass rises past its usual location, you leave the ground
with an initial velocity v, and you reach a...
