A dockworker loading crates on a ship finds that a 18-kg crate, initially at rest on a horizontal surface, requires a 85-N horizontal force to set it in motion. However, after the crate is in motion, a horizontal force of 55 N is required to keep it moving with a constant speed. Find the coefficients of static and kinetic friction between crate and floor.
determine the value of IG. The support at B does not move while the measurement is taken. For the calculation, the horizontal location of G should be determined.
A parallel-plate capacitor has an area of 5.15 cm2, and the plates are separated by 1.05 mm with air between them. It stores a charge of 337pC. What is the potential difference across plates of the capacitor.
A particle with a charge of -1.5uC and a mass of 2.5x10-6 kg is released from rest at point A and accelerates toward point B, arriving there with a speed of 42 m/s. The only force acting on the particle is the electric force. (a) Which point is at..
A computer disk is 8.0 in diameter. A reference dot on the edge of the disk is initially located at the disk accelerates steadily for 0.50, reaching 2000.
By what factor would its kinetic energy decrease if the car traveled half as fast
