- Your car rides on springs, so it will have a natural frequency of oscillation. Figure P14.48 shows data for the amplitude of motion of a car driven at different frequencies. The car is driven at 20 mph over a washboard road with bumps spaced 10 feet apart; the resulting ride is quite bouncy. Should the driver speed up or slow down for a smoother ride?15-22 need solution1) A2 Kg block is hanging on a frictionless inclined plane attached to a springwith a spring constantk 150 N/m. The spring is massless and it has an un-stretched length of 65 cm. a) If the spring is stretched and set in SHM: i) What is the frequency of the motion? i) What is the period of the motion? b) What is the equilibrium point of the block from the top of the inclined plane? 30°
- 49. John visits a space camp during the summer break. During this visit, John sits in a chair mounted to springs which undergoes simple harmonic motion. During this time, the motion is measured electronically and zaim's mass, along with the mass of the chair are taken into account. John notes the spring has a spring constant of 516N/m and the mass of the chair is 26.0 kg. If the period of oscillation zaim notes is 2.31 s what is John's weight?
