An automobile traveling on a straight, level road at 33 km/h speeds up to 64 km/h in
17 s. What was the magnitude of the auto's acceleration, in meters per second
squared?
Your Answer:
Answer

Expert Solution

Step 1

Given data:

Initial speed of automobile is, $u = 33 km / h = (33 km / h \times \frac{\frac{1000}{3600} m / s}{1 km / h}) = 9.17 m / s$ .

Final speed of automobile is, $v = 64 km / h = (64 km / h \times \frac{\frac{1000}{3600} m / s}{1 km / h}) = 17.78 m / s$ .

Time interval is, $t = 17 s$ .

In SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably mole comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical Intuition. More precisely, show that (a) 1.0m/s=3.6km/h and 1.0m/s=2.2mi/h .
