A1000 kg car is moving south with a speed of 20 m/s. how fast would a 100 kg bicyclist have to travel in order to have the same momentum? ?

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
