Question:
In one contest at the county fair, seen in Figure CP4.78, a spring loaded plunger launches a ball at a speed of 3.0 m/s from one corner of a smooth, flat board that is tilted up at a 20° angle. To win, you must make the ball hit a small target at the adjacent corner, 2.50 m away. At what angle θ should you tilt the ball launcher?

I am certain that with my dedication, hard work and commitment I can serve you well. I am a quick learner and I adopt flexible methods of handling different situations. Should my application be successful, I promise to do my very best in connecting with the students to make a positive difference.
