Question

A car moving initially at 54 mi/h begins decelerating at a constant rate 130 ft short of a stoplight. Part A If the car comes to a full stop just at the light, what is the magnitude of its acceleration? Express your answer with the appropriate units.

Step 1

To convert from miles per hour to feet per second, we need to multiply the initial velocity by a conversion factor. There are 5280 feet in a mile and 3600 seconds in an hour. Initial velocity in feet per second = 54 mi/h * (5280 ft/mi) / (3600 s/h) Show more…
