Homework Statement A block mass M slides down the side of a frictionless circle Radius R. At an angle Theta the mass M flies off the circle, what is the angle? Homework Equations PE(top) = KE(point it flies off) + PE(at that point) Arad = V^2 / R Sum Of Forces = Mass *...

Wow I actually got this one :) You are given the velocity V of the Train (25m/s) and the radius R of the circle (1000m) From this you can use the formula Radial Acceleration Arad = V^2 / R to get the Radial Acceleration (That is the acceleration toward the center of the circle to make the...

[SOLVED] Rocket Height (Motion in streight line) Hey I'm 75% sure i have the correct answer, but i have to turn it in tomorrow and it's a lot of points so i just want to make sure I'm going it right. Homework Statement A rocket, initially at rest on the ground, accelerates straight upward...

Now that I completed that the homework is asking me another question. Homework Statement How long is the flea in the air from the time it jumps to the time it hits the ground? Express your answer in seconds to three significant figures. x = .550m [Vsub0] = 3.28m/s (ans to 1) [Asubx] =...

[SOLVED] Just Checking Homework Statement In this problem, you will apply kinematic equations to a jumping flea. Take the magnitude of free-fall acceleration to be 9.80 . A flea jumps straight up to a maximum height of 0.550m . What is its initial velocity Vsub0 as it leaves the ground...
