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.

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.

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.

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...
