014 (part 1 of 2) You drop a stone from a position of rest. How far will it fall vertically in the ﬁrst 2 s? The acceleration of gravity is 9.8 m/s 2 . Answer in units of m 015 (part 2 of 2) If you instead toss it horizontally at 2.7 m/s, how far will it fall vertically...
Does every moving body possess kinetic energy? Does every stationary body possess potential energy?
ke=1/2 (mass)(velocity) ke=1/2mv^2 ke= 1/2m(10^2-0^2) ke=1/2m(20^2-10^2) ke=1/2m(100) ke=1/2m(400-100) ratio is 300/100 or 3/1
chemistry -- radioactive decay
suppose you have a 150 gram sample of radioactive decay god-191 which has a half- life of 3.4 hours. how many grams of gold will ramain after 10hrs ? after 24 hrs? answer : 10 hrs :10/3.4= 2.94 times 150*(1/2)^2.94 = 18.75 grams 24 hrs: 24/3.4 = 7.06 150*(1/2)^7.06= 1.12 right...
