I am doing a very similar problem right now, and I don't understand how you were able to determine what T1 or T2 were equal to.

its asking for omega in rad/sec & alpha in rad/sec^2... would that affect my answers any?

Homework Statement A rock stuck in the tread of a 53.0 cm diameter bicycle wheel has a tangential speed of 3.50 m/s. When the brakes are applied, the rock's tangential deceleration is 1.20 m/s^2. X.) What is the magnitudes of the rock's angular velocity (omega) when t = 1.60s? Y.) What is...

so what is the equation for P.E. then, cause I thought it was -1/2kx^2... So... EPIC fail... 5g = .05kg My answer WAS correct, the decimal place was just off by one...

nevermind! I figured it out! P.E. = 9.8(4.5)(.97) = 42.777J 42.777/.23 = 185.987W & 746W = 1hp 185.987/746 = .249hp

No, I"m not sure what the equation for gravitational potential energy is...

Homework Statement A 4.50 cat leaps from the floor to the top of a 97.0-cm-high table. If the cat pushes against the floor for 0.230 to accomplish this feat, what was her average power output during the pushoff period? Answer in terms of horsepower. Homework Equations W = Fdx F = ma...

Homework Statement A 50 g ice cube can slide without friction up and down a 30 degree slope. The ice cube is pressed against a spring at the bottom of the slope, compressing the spring 10 cm. The spring constant is 25 N/m. When the ice cube is released, what total distance will it travel up...
