A77 g frisbee is thrown from a point 0.99 m above the ground with a speed of 15 m/s. when it has reached a height of 1.3 m, its speed is 12 m/s. what was the reduction in the mechanical energy of the frisbee-earth system because of air drag?

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?

You throw a ball upward and let it fall to the ground. your friend drops an identical ball straight down to the ground from the same height. is the change in kinetic energy (from just after the ball is released until just before it hits the ground) of your ball greater than, less than, or equal to the change in kinetic energy of your friend's ball?
