Q. A flight attendant pulls her 63N flight bag a distance of 312m along a level airport floor at a constant velocity. The force she exerts is 39N at the angle of 59° above the horizontal.
A: Find out the work she does on the flight bag.
B: determine the work done by the force of friction on the flight bag.
C: determine the coefficient of kinetic friction between the flight bag and floor.
The coefficient of kinetic friction
An electron has an initial velocity of (15.0 j + 22.0 k) km/s and the constant acceleration of (3.00*10^12 m/s^22)i in a region in which uniform electric and magnetic fields are present. If B = (400 µT)i, find the electric field E.
A conveyor belt at a quarry lifts 2,000 kg of sand per minute up a vertical distance of 12 meters. The sand is at first at rest, then moves at a speed of 0.20 m/s along conveyor belt. What is the instantaneous power generated by this machine .
