An earth-like planet has a mass of 5.00×1024 kg and a radius of 4000 km. What is the gravitational field, g, on the surface of this planet? (We can simplify the Gravitational Constant G to 6.7x10-11 Nm2/kg) N/kg Submit Answer Tries 0/2 What is the force of gravity on an 89 kg alien standing on the surface of this planet?

a.) Calculate the gravitational force exerted on earth by the moon. b.) Calculate the gravitational force exerted on earth by the sun. c.) What is the Net gravitational force exerted on the earth.

Example 4. A satellite is orbiting a circular orbit at an altitude of 900 km, at which atmosphere density is 5.46 x 10-13kg/m³. The satellite has mass 150kg, cross sectional area 1.50m², and drag coefficient 2. a) Calculate the rate of change of orbit radius da/dt in units of m/s. b) Make an estimate of the time (in years) that will take the satellite to reach the Earth.

Task 1: Gravitational Fields 1. A person with a mass of 60 kg is inside a rocket that is moving straight up, away from the earth's surface. The radius of the earth is 6.38 x 105 m and the mass of the earth is 5.98 x 1024 kg. a. Find the force of gravity acting on the person at an altitude of 300 000 m. b. Find the altitude that will cause the person's weight to drop to one-quarter of its value on the earth's surface. 2. Mass 1 is four times as large as mass 2. Both masses are at rest and are separated by 200 m. Where could you place a third mass, mass 3, if the net force on 3 must be zero?

Can someone help me?? With all the steps thank you.

We all know the Earth exerts gravity on us, but other objects in the solar system also pull on us. In the following series of problems we will investigate how strong gravity is for a person standing on the surface of the Earth from various objects in the solar system. You can answer the following series of questions using Newton's Law of Gravity; use the units given and the Gravitational Constant, G = 6.67 ×10 -11 m 3 /kg/s 2   10: What is the force of gravity due to the Moon on a 60.0  kg ASTR 110 student standing on the equator during Spring Break. DATA: mean distance to the Moon 3.84×108 meters; mass of the Moon 7.36×1022 kg.   using the right formula: Fg = (G M1 M2 / d^2)

An 800 kg satellite orbits Earth and take one day for complete orbit. Earth has a radiu 6,372 km and a mass of 5.972 x 10^24.   A. If the radius of orbit is constant, find the altitude of the satellite above Earth's surface. B. Find the orbital speed of the satellite  C. The satellite suddenly turns off, stops moving and heads straight towards the surface of Earth. At what speed will the satellite crash into the Earth's surface? (Hint: Use energy conservation)
