If you shoot a cannonball from the same cannon first at 30 and then at 60 relative to the horizontal, which orientation of the cannon will make the ball go farther? Ignore air resistance.
1. The angle of 30 will make the ball go farther.
2. The angle of 60 will make the ball go farther
3. Both angles will make the ball land at the same distance
Describe why.
In an L-R-C series circuit, the resistance is 360 ohms, the inductance is 0.360 henrys, and the capacitance is 1.20×10?2 microfarads. What is the resonance angular frequency ?0 of the circuit? (answer should be in rad/s)
