An automobile manufacturer is testing the suspension system of their latest car model. They load the car, which has a mass of 1,110 kg, with four test dummies, each with a mass of 71.9 kg. The car is placed onto a horizontal platform which can oscillate vertically with an adjustable frequency. The engineers find that when the platform's frequency is set to 1.70 Hz, the car's suspension vibrates at its maximum amplitude. The platform oscillation is then turned off. As four test dummies are removed from the car, the car's body will rise by what distance (in cm)? X 14.7 TE +h

A 50-cmcm-long spring is suspended from the ceiling. A 250 gg mass is connected to the end and held at rest with the spring unstretched. The mass is released and falls, stretching the spring by 20 cmcm before coming to rest at its lowest point. It then continues to oscillate vertically. Part A: What is the spring constant? Part B: What is the amplitude of the oscillation? Part C: What is the frequency of the oscillation?

A simple harmonic oscillator consists of a 2.0-kg block and a 1200-N/m spring. When the block is 3.5 cm from equilibrium, its velocity is 85 cm/s. What is the amplitude of the oscillator? 4.9 cm 7.3 cm 17 cm 31 cm 12 cm

In the figure provided, two boxes oscillate on a frictionless surface. The coefficient of static friction between the two boxes is 0.440 and the spring constant in the spring is 54.5 N/m. If the smaller box has a mass of 3.51 kg and the larger box has a mass of 8.47 kg, what is the maximum oscillation amplitude for which the 3.51 kg box does not slip?
