1. For all problems, ignore friction and air resistance [1] How long will it take a 14. n object to free fall from a height of 50 meters? Does the fact that it weights 14. n matter? Explain.

2. [2] An object initially moving at 3.0 m/s is accelerated 1.5 m/s/s for 8.0 seconds. What is its final speed?

3. [3] Starting at rest, an object rolls freely down inclined plane in 2.0 sec. and attains a final speed of 19.6 m/s. What is the object’s acceleration

4. [4] An object, initially at rest, is accelerated 1.0 ms/s/ for a distance of 100 meters. What is its final speed?
