- Calculate the force F on one side of a circular plate with radius 5 m, submerged vertically in a tank of water so that the top of the circle is tangent to the water surface. The acceleration for gravity is 9.8 m/s². The density of water is 1000 kg/m³. (Use symbolic notation and fractions where needed.) F = Narrow_forwardHow much work is required to lift a 900-kg satellite to an altitude of 1⋅1061⋅106 m above the surface of the earth? The gravitational force is F=GMm/r2F=GMm/r2, where MM is the mass of the earth, mm is the mass of the satellite, and rr is the distance between them. The radius of the earth is 6.4⋅1066.4⋅106 m, its mass is 6⋅10246⋅1024 kg, and in these units the gravitational constant, GG, is 6.67⋅10−11arrow_forwardFind the net change in velocity over [4, 16] of an object with the acceleration a(t) = 27 (in m/s²).

- You throw a ball (from ground level) of mass 1 kilogram upward with a velocity of v = 31 m/s on Mars, where the force of gravity is g = - 3.711 s2 A. Approximate how long will the ball be in the air on Mars? B. Approximate how high the ball will go?arrow_forwardHow much work is required to lift a 800-kg satellite to an altitude of 3. 106 m above the surface of the Earth? The gravitational force is F = GMm/r², where M is the mass of the Earth, m is the mass of the satellite, and r is the distance between the satellite and the Earth's center. The radius of the Earth is 6.4. 106 m, its mass is 6 · 1024 kg, and in these units the gravitational constant, G, is 6.67 · 10-11.
