According to recent test data, an automobile travels 0.250 mi in 19.9 s, starting from rest. The same car, when braking from 60.0 mi/h on dry pavement, stops in 146 ft. Assume constant acceleration in each part of the motion, but not necessarily the same acceleration when slowing down as when speeding up. A) Find the acceleration of this car when it is braking. B) If its acceleration is constant, how fast (in mi/h) should this car be traveling after...
How much energy is dissipated in braking a 1200-Kg car to a stop from an initial speed of 30 m/s?
Calculate the braking force needed to stop the wheels in a 100kg car from spinning at 70km/h in 5s
Part A During a very quick stop, a car decelerates at 7.40 m/s. What is the angular acceleration of its 0.280-m-radius tires, assuming they do not slip on the pavement? Submit Answer Incompatible units. No conversion found been rpn' and the required units. Tries 0/5 Previous Tries Part B How many revolutions do the tires make before coming to rest, given their initial angular velocity is 90.0 rad/s. (You do not need to enter any units.)

A car moving initially at a speed of 52.0 mi/h and weighing 3,000 lb is brought to a stop in a distance of 205 ft. Find (a) the breaking force (b) the time required to stop. Assuming the same braking force find (a) the distance and (d) the time required to stop if the car were going 26.0mi/h initially. (Hint: Convert to SI units)
How long does it take an automobile traveling in the left lane of a highway at 60.0 km/h to overtake (become even with) another car that is traveling in the right lane at 20.0 km/h when the cars' front bumpers are initially 75 m apart?
Exercise 2.33 A car moving initially at 58 mi/h begins decelerating at a constant rate 140 ft short of a stoplight.
