A flywheel with a radius of 0.500m starts from rest and accelerates with a constant angular acceleration of 0.500rad/s2.
a) Compute the magnitude of the radial acceleration of a point on its rim after it has turned through 60.0?
b) Compute the magnitude of the tangential acceleration of a point on its rim after it has turned through 120.0?
c) Compute the magnitude of the radial acceleration of a point on its rim after it has turned through 120.0?
What is the phase constant of the motion and what are its position and direction of travel at t = 2.00 s, what is the first time when the object is at maximum velocity?
Consider three containers of the same volume that are thermally insulated (no heat is transferred) from each other, but are connected by thin pipes that allow gas to pass freely from one to another.
An object is placed 13.1 cm to the left of a diverging lens of focal length -6.04 cm. Find the distance d that places the final image at infinity
A cubical box is filled with sand and weighs 798 N. We wish to "roll" the box by pushing horizontally on one of the upper edges. What minimum coefficient of static friction between box and floor is required
Three charged particles are fixed to an x axis: Particle 1 of charge q1 = 2.1e-8 C is at position x=20 cm and particle 2 of charge q2 = 2.00q1 is at position x = 30 cm, particle 3 of charge q3 = -4.00q1 is at position x = 70 cm.
Velocity and time for the moving particle.
A 48.0 ice skater spins about a vertical axis through her body with her arms horizontally outstretched, making 2.50 turns each second. The distance from one hand to the other is 1.50. Biometric measurements indicate that each hand typically makes ..
