- The block is at rest as shown. What is the peiod of the oscillation if the block is pulled down by 10 cm, in seconds? Use g = 10 m/s². Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. 100 g 10 20 30 40 50 60 70 80 90A scientist wishes to determine the acceleration of gravity on the surface of the planet Nos'Kere by experimenting with a pendulum. The length of the pendulum is 3.2 m, and the period of the pendulum is 2.3 s. unitWhat is the length, in meters, of a simple pendulum, on Earth, if it has a frequency of 0.72 Hz?
- Answer must be in scientific notation with SI units that do not have prefixes except for kg. (m/s not cm/s). Answer must be in standard form scientific notation. All angles are to be calculated to the nearest 0.1 deg (tenth of a degree).A mass m = 1.9 kg is at the end of a horizontal spring on a frictionless horizontal surface. The mass is oscillating with an amplitude A = 4.5 cm and a frequency f = 1.05 Hz. Part (a) Write an equation for the spring constant k. Part (b) Calculate the spring constant k, in Newtons per meter. Part (c) Write an equation for the total mechanical energy, E, of the motion. Your expression should be in terms of the variables in the original problem statement. Part (d) Calculate the total mechanical energy E, in joules.A 0.95 kg mass hanging from a spring oscillates up and down according to the equation z(t) = (6.34 cm) sin ( (8.53 rad/s)t + π/4 ). What is the spring constant of the spring? Give your answer in units of N/m.
