How long will it take for a car to accelerate to come to a stop if it is traveling at 20m/s and the car has a maximum decelerati on of 6m/s
1 answer:
When the car comes to a stop, the final velocity must be 0 m/s. Since the car js decelerating in a forward direction, acceleration must be negative. final v = initial v + a•t 0 = 20 + (-6)t t = 3.33s

D is the wrong answer. New information does often completely change the theory. Its hard to change something and leave the major theory intact.
The force applied would be 1.05*9.8 = 10.3 N the pressure is equal to F/a area will be πr^2 = 0.002826 thus pressure will be = 10.3/0.002826= 3644.72 N/m^2
