Question

1) A toy ball swings in a horiztonal circle 2.4 meters in diameter making 45 revolutions in 1.7 minutes. The shadow of the ball is projected to the wall by a distant light. What are the amplitude, frequency and period for the shadows motion?

Amplitude = XXXX meters

Frequency = XXXXX Hertz

Period = XXXX seconds

2) A 2.7 kg mass oscillates at the end of a spring in SHM. The amplitude of the vibration is 20 cm and the spring constant is 65 N/m. What is the acceleration and force on the object when it is located 5 cm from the origin?

Acceleration = XXXX m/s2

Force = XXX Newtons

Explanation / Answer

1) Amplitude = A = Radius = 1.2 m

    Frequency = f = 45(rev/min)/60 = 0.75 rav/s

    Period = T = 1/f = 1.333 sec
