Document Summary
2/s: m, m/s, a freely falling object, has a uniformly increasing velocity, is unaffected by gravity, has a uniformly increasing acceleration, has a uniformly increasing displacement, two equal and opposite forces of 3. 0 n act on an object. 2: 40 n, 1. 6 n, 0. 63 n, 13 n, if a person weighs 150 lb on earth, that person"s weight on the moon would be, 112. 79 n: 1500 n, 240 n, 186 n, 93 n, if an object of mass 8 kg has an acceleration of 5 m/s , what is the unbalanced. 2: a car is moving down a freeway in a straight line at a constant rate of 20. 0 m/s for 4. 0 s. its acceleration is. 2: 9. 8 m/s , 9. 8 m/s, zero, 5 m/s, 6. 0 m/s . Physical science psc2121: a system of two electrons, two protons, and five neutrons has a net charge of, +1. 6 10, 1. 6 10, 3. 2 10 -19, zero.
, and 
and 
. The object experiences an acceleration of magnitude 3.75 m/s2.
