The tires of a car make 91 revolutions as the car reduces its speed uniformly from 86.0 km/h to 56.0 km/h. The tires have a diameter of 0.88 m angular acceleration: α = -1.5 rad/s^2
Part A:
If the car continues to decelerate at this rate, how much more time is required for it to stop?
Express your answer to two significant figures and include the appropriate units.
Part B:
If the car continues to decelerate at this rate, how far does it go? Find the total distance.
Express your answer to three significant figures and include the appropriate units.
In the quark model of fundamental particles, a proton is composed of three quarks: two "up" quarks, each having charge +2e/3, and one "down" quark, having charge -e/3. Suppose that the three quarks are equidistant from one another. Take the distance ..
