A place kicker should kick a football from a point 35m, Ask an Expert

Academics

Q. A place kicker should kick a football from a point 35m (about 38.0 yd) from the goal, and the ball should clear the crossbar, which is 3.05 m high. When kicked, ball leaves the ground with a speed of 21.0 m/s at an angle of 55° to the horizontal.

Q. A 50 Omega resistor, a 0.1 H inductor, and a 10-mu F capacitor are connected in series to a 60-Hz source. The rms current in the circuit is 3 A. Find out the rms voltage across the resistor, the inductor and capacitor.
