Physics
acceleration and velocity are two different things. try using.. d = vt + (1/2)a(t^2)
physics
acceleration = change in velocity / change in time so.. a = 10 - 0 / 1.35 a = 7.41 m/s^2
math
A straight road up a hill has a slope of 1/4. From the bottom of the hil to the top of the hill, the horizontal change is 80 m. Determine the height of the hill. I'm thinking that it's 80/4 = 20 m.. but I'm not 100% sure.
physics - special relativity
whoops.. wrote it wrong.. should be.. 0.6m = (mv) / (square root 1 - (v/c)^2) and that's as far as i got.. i don't know what to do from there or if it's the right equation :S
physics - special relativity
When a rocket is moving at a constant speed, it has a relativistic mass that is 60 percent greater than its rest mass. Find the speed of the rocket. **** So far, I tried using the relativistic mass equation.. 0.6m = mv / square root 1-(v/c)2
Algebra
-5x > 0 -5x/-5 > 0/-5 x < 0 since we are dividing by a negative, the inequality changes so, no the answer is not the same 9x > 81 x > 81/9 x > 9
