Answer #1

given mass m = 10 kg

and force F = 120 N

F - mg = ma

120 N - (10*9.8) = (10) a

a = 2.2 m/s2

    Unit 2 Newton's Laws .. What is the acceleration a of an m = 11 kg pail of cement (or a rock) when pulled upward (not sideways!) on a rope by a person with a tensional force of FT = 120 N? (Hint: you need the pail's weight as well.) The result that you get for the acceleration (about 0.1 to 0.9 m/s2) is more realistic than the one originally in the textbook. Note also that I included "by a...
