You live on a planet far from ours. Based on extensive communicationwith a physicist on earth, you have determined that all lawsof physics on your planet are the same as ours and you have adopted thesame units of seconds and meters as on earth. But you suspect that thevalue of g, the acceleration of an object in free fall near the surface ofyour planet, is different from what it is on earth. To test this, you take asolid uniform cylinder and let it roll down an incline. The vertical height hof the top of the incline above the lower end of the incline can bevaried. You measure the speed vcm of the center of mass of the cylinderwhen it reaches the bottom for various values of h. You plot v 2cm (inm2/s2) versus h (in m) and find that your data lie close to a straight linewith a slope of 6.42 m/s2. What is the value of g on your planet?
You go where no one has gone before and discover an interesting planet of radius r. When you arrive, you clearly want to do some experiments to learn more about this world. You begin with some simple kinematics and measure the time t for an object thrown directly up with velocity vi to return to your hand. With this information, you find that the acceleration due to gravity gi s much lower than on Earth. a) You decide to orbit the planet in your spacecraft at a distance Rabove the surface of the planet. Find the time required to complete one orbit in terms of R, r, vi, t, and any necessary constants. b) FInd the escape velocity ve–the initial velocity necessary for an object to barely escape the gravitational pull of the planet. Express your answer in terms of vi, r, t,and any necessary constants. c) Find the distance from the planet’s center at which an object launched from the surface with velocity vwill have lost 90% of its initial kinetic energy at the surface in terms of v,vi, r,…
The NEXT morning, you wake up in a strange room yet again, and this time you drop a ball from a height of 1.54 m above the floor. The ball hits the floor 0.392 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)? 10.0 m/s^2 15.0 m/s^2 30.0 m/s^2 20.0 m/s^2
Concern the planet Mars, which has a radius of 3400 km On Mars, the acceleration due to gravity is 3.72 m/s2 . a. Assuming that the centripetal acceleration at the Mars equator is equal to the acceleration due to gravity, estimate the length of a day on Mars. Note: this does not give a good estimate of the length of a day on Mars! b. Using only information provided above, estimate the mass of Mars. Is this value a good estimate? c. If the radius of Mars suddenly were to double (without changing its mass), what would be the new acceleration due to gravity? Would you expect the length of a day on Mars increase, decrease, or stay the same?
Planet X was just discovered orbitinga nearby star! It orbits a start that is 6.9 times themass of our sun in a solar system just 31.3 light-years away. The acceleration due to gravity thereis 0.07 g. After making some measurements in lab, you start to daydream about travel to other planets. Your spring gun can launch a projectile with a speed of 3.7 m/s. What would happen if you were tolaunch a projectile at an angle of 32 ° abovehorizontal on Planet X? (a) What maximum height would the projectilereach?(b) How far would the projectile travel before ithit the ground? Assume the projectile lands at the same height it was launched from.
Could someone please explain? Thank you.
As their booster rockets separate, Space Shuttle astronauts typically feel accelerations up to 3g, where g = 9.80 m/s2. In their training, astronauts ride in a device where they experience such an acceleration as a centripetal acceleration. Specifically, the astronaut is fastened securely at the end of a mechanical arm, which then turns at constant speed in a horizontal circle. Determine the rotation rate, in revolutions per second, required to give an astronaut a centripetal acceleration of 3.00g while in circular motion with radius 9.45 m.

An object is moving with an initial velocity of 5.8 i m/s and a final velocity 13.8 i m/s. The time taken for acceleration is 2.2 seconds. Calculate the acceleration in m/s2 to 2 sf. In your answer, you do not enter the i unit vector, but you do need to enter negative signs, if appropriate. e.g. if your answer is a = -5.4 i m/s,2 you would enter -5.4
