A conical pendulum is formed by attaching a 0.400kg ball to a 1.00m -long string, then allowing the mass to move in a horizontal circle of radius 40.0cm. The figure shows that the string traces out the surface of a cone, hence the name.
What is the tension in the string?
What is the ball's angular velocity, in rpm?
Discover the tensions in the rope
A 5,000 kg satellite is orbiting the Earth in a circular path. The height of the satellite above the surface of the Earth is 800km. The velocity of the satellite is (Me = 5.98 x 10^24 kg, Re = 6.37 x 10^6 m, G = 6.67 x 10-11 N • m2/kg2)
What is the horizontal distance between elbow and the point where the weight of the forearm acts.
For the Atwood's machine, suppose the masses have an initial speed of v = 0.22 m/s and that m2 is moving upward. How high does m2 rise above its initial position before momentarily coming to rest, given that m1 = 3.5 kg and m2 = 3.1 kg.
A 23.00 kg chair initially at rest on a horizontal floor requires a 364N horizontal force to set it in motion. Once the chair is in motion, a 328N horizontal force keeps it moving at a constant velocity. A 23.00 kg chair initially at rest on a horizo..
A - 5.00 nC point charge is on the x axis at x = 1.20 m . A second point charge Q is on the x axis at -0.600m. a) What must be the sign and magnitude of Q for the resultant electric field at the origin to be 45.0N/C in the + x direction?

A 47-g golf ball is driven from the tee with an initial speed of 52.0 m/s and rises to a height of 24.2 m.
A 48.21 {rm kg} ice skater spins about the vertical axis through her body with her arms horizontally outstretched, making 2.20 turns each second. The distance from one hand to the other is 1.5 {rm m}. Biometric measurements indicate that each hand na..
what common temperature must the two pieces be heated.
A 9.22 kg ball, hanging from the ceiling by the light wire 145.00 cm long, is struck in an elastic collision by a 1.20 kg ball moving horizontally at 6.46 m/s just before the collision.
What is the total momentum of system after the collision.
