Could you explain to me where exactly that fraction came from?

Homework Statement Simplify. Write as positive exponent c(c^5/6)/c^2 Homework Equations None really, just exponent laws. The Attempt at a Solution c(c^5/6) comes out as... c^5/6 Dividing exponents requires subtracting them so... 5/6 - 2/1 Find common denominator... 5/6 -...

Homework Statement This isn't really a specific question, I just need clarification on multiplying a radical expression If I were to do... x multiplied by 4√6, which number would receive the variable x when multiplied? Homework Equations The Attempt at a Solution

Homework Statement 2n - 6m + 5n^2 - 15mn Homework Equations No particular equation since this is factoring The Attempt at a Solution Keep in mind that I struggle when it comes to grouping as I'm not sure where I'm supposed to start but... 2n - 6m + 5n^2 - 15mn Group first 2...

Wait So there are 2 separate velocities? Doesn't the velocity stay constant throughout the entire thing(at least until it hits the ground)? Plus the ball is being thrown at an angle, 2.7m/s should apply for both the X axis and the Y axis.

I actually already know what the answers are It's finding out how to get to those answers is the problem.

Homework Statement During the opening kickoff of a college football game, the kicker kicks a football with an initial velocity of 27.5m/s at an angle of 41 degrees above horizontal. What is the flight time for the ball? What is the maximum height How far does it travel before hitting the...

Homework Statement A roller coaster starts at rest from a height of 110m and accelerates down the track to a height of 10.0 m. Find the speed it can each, assuming there is no friction Homework Equations Eg = mgh v = sqrt(2Ek/m) The Attempt at a Solution Honestly I'm not sure...

Homework Statement A student throws 0.22kg rock horizontally at 20.0m/s from 10.0m above the ground. Ignore air resistance. Find the initial kinetic energy of the rock Homework Equations Ek = mv^2/2 The Attempt at a Solution This sounds INCREDIBLY easy and every shape or form...

Unfortunately I've checked the answer for the question and there is indeed an applied force.

Homework Statement A person pushes a box across a horizontal floor with an initial velocity of 5.2m/s. The box has a mass of 22kg, and the coefficient of Kinetic friction between the box and the floor is 0.44. How far does the box slide before coming to rest? Homework Equations μk =...

Homework Statement An ice fishing hut weighing 52 N sits on a dry, frozen lake. What is the magnitude of the initial horizontal force required to make the ice fishing hut start sliding across the surface of the frozen pond Homework Equations μk = Fk/Fn or μs = Fs/Fn The Attempt...
