When you drop a 0.41 kg apple, earth exerts a force on it that accelerates it at 9.8 m/s 2 toward the earth’s surface. according to newton’s third law, the apple must exert an equal but opposite force on earth. if the mass of the earth 5.98 × 1024 kg, what is the magnitude of the earth’s acceleration toward the apple? answer in units of m/s 2 .

28. a stone is projected at a cliff of height h with an initial speed of 42.0 mls directed at angle θ0 = 60.0° above the horizontal. the stone strikes at a, 5.50 s after launching. find (a) the height h of the cliff, (b) the speed of the stone just before impact at a, and (c) the maximum height h reached above the grou

Contrast the force of gravity between these pairs of objects a 1 kg mass and a 2 kg mass that are 1 m apart and two 2 kg masses that are 1 m apart
