A worker pushed a 30.0 kg block 6.50 m along a level floor at constant speed with a force directed 30.0° below the horizontal. If the coefficient of kinetic friction between block and floor was 0.190, what were (a) the work done by the worker's force and (b) the increase in thermal energy of the block-floor system?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
