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)

340-lb carriage has an initial velocity of 6.3 ft/sec down the
incline at A, when a constant force of 120 lb is applied to the
hoisting cable as shown. Calculate the velocity of the carriage
when it reaches B. Show that in the absence of friction this
velocity is independent of whether the initial velocity of the
carriage at A was up or down the incline.

The 190-lb carriage has an initial velocity of 10.3 ft/sec down
the incline at A, when a constant force of 65 lb is
applied to the hoisting cable as shown. Calculate the velocity of
the carriage when it reaches B. Show that in the absence
of friction this velocity is independent of whether the initial
velocity of the carriage at A was up or down the
incline.
