At what height (in km) above the surface of Earth would the gravitational ?acceleration be 6.6 m/s-

The standard acceleration of gravity at the earth's surface is g=9.81m/s2. Convert this acceleration to units of inches/min2.

7.) A sateltle orbits at a height of 6,000 km above the earth’s surface. REarth = 6.38 × 106 m, mEarth = 5.98 × 1024 kg. What is the magnitude of the gravitational acceleration g at this height, in m/s2? Use G = 6.67 × 10-11 N·m2/kg2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

At what distance above the surface of the earth is the acceleration due to the earth's gravity 0.665 m/s2m/s2 if the acceleration due to gravity at the surface has magnitude 9.80 m/s2?m/s2? Express your answer in meters.

A car driving around a circular track has a centripetal acceleration of 97 m/s2 until it hits a slick spot and slides straight off the track. If the radius of the track is 61 m, what is the car's speed v when it leaves the track?

You have a mass of 70kg and are standing 6 meters away from a tractor-trailer. You feel a gravitational force of 7.85N. What is the mass of the tractor-trailer?

Calculate the numerical values of the accelerations experienced by objects near the surface of Earth due to the following. Assume uniform circular motion a = w²r. a) Earth's gravity (A: 9.8m) b) Earth's rotation about its own axis (4:0.034) c) Earth's revolution around the Sun. (A: 0.006)

A rocket is launched and attains a speed of 5700_m/s when 63000_m above the surface of the Earth. If the engines then shut down, how much higher will the rocket rise before beginning its fall back toward the Earth? А. 4066000_m D. 2353000_m В. 1703000_m Е. 3876000_m С. 2292000_m F. 3573000_m
