A single axle trailer has a sole set of wheels; a tandem axle has two sets of wheels. Simple counting can tell you which type of trailer youâre looking at, making it easy to compare trailers and determine which one suits your needs best.
A pendulum makes 36 vibrations in exactly 60 s. What is its (a) period, and (b) frequency? 7. How long must a simple pendulum be if it is to make exactly one swing per second? (That is, one complete vibration takes exactly 2.0 s.) 8.. If a simple pendulum whose length is 1.50 m makes 72 oscillations in 3.00 min, what is the acceleration of gravity at its location? 5. A 2500 kg demolition ball swings on a cable 17.0 m long.
6. Use Figure 1 to estimate the period of a pendulum with a length of 90 cm and a mass of 200.0 grams that is released from an angle of 30Â°. a. 1.88 seconds b. 2.00 seconds c. 2.14 seconds d. 2.90 seconds 7.A 130-cm length pendulum consisting of a 200.0-gram mass is released from an angle of 30Â°.se Figure 2 to estimate the period of a pendulum with a length of 65 cm and a mass of 400.0 grams that is released from an angle of 30Â°. a. 0.81 seconds b. 1.30 seconds c. 1.63 seconds d. Nonsense! It is impossible to make such an estimate since no pattern exists. 11.
