Question

The makers of a certain automobile advertise that it will accelerate from 15 to 50 mi/hr in 10 s. Assume that

the acceleration is constant, Compute the distance the car travels for a period of 10 sec.

Answer 1

The acceleration is

$$a=\frac{\Delta v}{t}=\frac{50-15}{10}=3.5\text{ mi/(hr}·\text{s}).$$
