1)
first you find the maxium force that the car can produce.
f=ma
Fmax=(1100kg)(6m/s^2)
then use f = ma again to find the accel with the passengers
Fmax=(1100kg +1650kg)(a)
=> a = (1100kg)(6m/s^2)/( 1100kg +1650kg)
= 2.4 m/s^2
Speed (ex: meters/second, miles/hour)
The answer to this question would be A. Interference. This is because when two sounds with slightly different frequencies creates a periodic variation in volume.
