a) What is the gravity of a planet if a R = 3 meter circulating mass m = 1 kg connected to a mass M = 4 kg, takes 2 seconds to circle once? b) If this same mass and string were to swing on the Earth, what would its period be? Please show ALL work and explanations. Thank you in advance.
a )
given
R = 3 m
m = 1 kg
M = 4 kg
T = 2 sec
using equation for acceleration is
a = 4 x R2 / T
= 4 x 3.14 x 32 / 2
so the acceleration a = 56.52 m/sec2
b )
g = 9.8 m/sec2
9.8 = 4 x R2 / T
T = 4 x 3.14 x 32 / 9.8
T = 11.534 sec
so the time period is T = 11.54054 sec

What is the acceleration due to gravity on a planet where a 1.5 m long pendulum oscillates with the same period as a 0.8 kg mass vibrates on an 80 N/m spring?
Find the force of gravity býtween a object (mass = 9.0 kg) and another planet (mass=8.6*10^ 23 kg) when the planet at its closest to Earth dis * tan c * e = 9.2x 10^ 10 m) . Express your answer to two significant figures and include the appropriate units. Using the formula for gravity, find the force of gravity on a 6.1 kg mass at Earth's surface. (The mass of Earth of 6*10^ 24 kg , and its radius...
You sit on Earth taking a physics test.a. What is the force of gravity from the planet Jupiter (mass = 1.9 * 1027kg) pulling on you (mass = 75kg) right now (distance = 5.9 * 1011m)? b. What is the force of gravity between you (still m = 75kg) and the Earth? HINT: you don’t need the mass of the Earth for this, just Newton’s second law! c. The Mass of Jupiter is over 300 times the mass of Earth. Why is...
Step 13: Let's find out the gravity on an unknown planet. Go back to the simulation, set the length of the pendulum equal to 1.0 m and mass of the bob equal to 0.1 kg. Select "Planet X" from the drop-down menu under Gravity. Measure the time period for the pendulum on Planet X. Record it below (for 10 oscillations) T Planet x = 16.995 Use this time period to find the gravity on Planet X. Show all your work...
please explain the answer 4) The escape velocity on the surface of a planet is given by 2GM R where G = 6.67 x 10-11m2 kg-1 3-2 is Newton's gravitational constant, M is the mass of the planet, and R is the radius of the planet. The escape velocity is the velocity you have to thrown an object so that it does not come back down (better hit the gym!). Write v in terms of average mass density p. Recall...
