A car's front suspension has a natural frequency of 0.45 Hz. The car's front shock absorbers are worn out, so they no longer provide critical damping. The car is driving on a bumpy road with bumps 42 m apart. At a certain speed, the driver notices that the car begins to shake violently.
What is this speed?

Which is not one of the major climate zones? question 3 options: rain forest polar tropical temperate

A2.0 μf capacitor and a 4.0 μf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
