Q3. [21pts] Four people of total mass 300 kg get into a car. The car springs are compressed and the body of the car is lowered by 3 cm. Whilst driving, the car hits a bump on the road and oscillates vertically with a period of 0.75 s. a. Derive the value of the spring constant for the car suspension (the acceleration due to gravity can be taken as g = 9.8 ms). b. Derive the total mass of the...

Four people enter a 2,150 kg vehicle and discover that this compress the vehicle's springs by an additional 0.75 cm. Together the people have a mass of 310 kg. If we pretend that the vehicle's suspension consists of one spring, then we can calculate its effective spring constant, k. What is the value of k (in N/m) for this vehicle? The four people exit the vehicle. They push down upon it once and then release it. This causes the vehicle...

+ M A platform of mass 0.8 kg is supported on four springs (only two springs are shown in the picture, but there are four). A chunk of modeling clay of mass 0.6 kg is held above the table and dropped so that it hits the table with a speed of v = 0.9 m/s. The clay sticks to the table so that the the table and clay oscillate up and down together. Finally, the table comes...

Car enthusiasts often lower their cars closer to the ground as a matter of style. James wants to lower his car by replacing all four of his original coil springs with new ones offered as an option by the car manufacturer. Note that changing the coil springs on a car can unsafely affect its handling. Consult your national or state laws before altering the suspension on any car. The new springs will be identical to the original springs, except the...
