Q. A potter's wheel having a radius 0.53 m and a moment of inertia 14.8 kg·m2 is rotating freely at 52 rev/min. The potter can stop the wheel in 6.0 s by pressing a wet rag against the rim and exerting a radially inward force of 65 N. Find the effective coefficient of kinetic friction between the wheel and the wet rag.
Q. A negative charge of -2.0 multiplied by 10-4 C and a positive charge of 9.5 multiplied by 10-4 C are separated by 0.30 m. What is the force between the two charges?
A negative charge of -6.0 multiplied by 10-6 C exerts an attractive force of 66 N on a second charge 0.054 m away. What is the magnitude of the second charge?
A 79, 37--long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 13 ball of clay travelling horizontally at 2.6 hits and sticks to the extremely bottom tip of the rod.
Calculate the horizontal force that must be applied to create an acceleratrion of 1.8g for a 1.2kg puck on a horizontal friction-free air table.
A car is driven 155 km west and then 75 km southwest. What is the displacement of the car from the point of origin (magnitude and direction).
A rocket blasts off vertically from rest on the launch pad with an upward acceleration of 2.30. At 10.0 after blastoff, the engines suddenly fail, which means that force they produce instantly stops.
The angular momentum of Earth is constant
A potter's wheel having a radius 0.55m and a moment of inertia 12kg•m2 is rotating freely at 51 rev/min. The potter can stop the wheel in 7 s by pressing a wet rag against the rim and exerting a radially inward force of 67N. Find out the effectual co..
A 50 hard-boiled egg moves on the end of a spring with force constant . It is released with an amplitude 0.300 . A damping force acts on the egg. After it oscillates for 5.00 , the amplitude of the motion has decreased to 0.100.
Different values of the energy
A wheel 65 cm in diameter accelerates uniformly from 215 rpm to 390 rpm in 6.0 s. How far will a point on the edge of the wheel have traveled in this time.
