A car hit a bump patch and starts to shake resonance is occurring because the bumps are occurring 1 wheel circumference apart the bumps. What speed is the car traveling rwheel=.4m k for suspension springs= 1.5x10^6n/m mass= 215kg

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

they should be similar or the same

answer and explanation;

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
