A 40.0-kg boy, riding a 2.50-kg skateboard at a velocity of +5.30m/s across a level sidewalk, jumps forward to leap over a wall.Just after leaving contact with the board, the boy's velocityr elative to the sidewalk is 6.00 m/s, 9.50o abovethe horizontal. Ignore any friction between the skateboard and the sidewalk. What is the skateboard's velocity relative to the sidewalk at this instant? Be sure to include the correct algebraicsign with your answer.
A resistance R and a 3.4-H inductance are in series across a 60-Hz ac voltage. The voltage across the resistor is 34 V and the voltage across the inductor is 39 V. Assume that all voltages in this problem are rms voltages. (a) What is the resistance ..
