If the velocity of the chair is constant, then the net force acting on it is zero.
The force you exert to keep it going is equal and opposite to the force of friction.
3 minutes = 180 seconds.
If it spent the entire 180 seconds slowing down at the rate of 3.5 m/s every second, then it began the 3 minutes at the speed of (180 x 3.5)=630 m/s. That's about 1,409 mph !

Answer:
The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

Answer:
The center of mass changes
Explanation:
The higher the center of mass the more likely things are to topple over but the lower it is the more likely to stay put when all 4 wheels are down .
