1. How far will a rock fall in 4.6 seconds? Recall that d = 1/2 at^2 for an object in free fall, and the acceleration due to gravity is always 10 m/s/s on Earth.
2. Determine the momentum of a 3-kg skateboard moving at 2.5 m/s. Recall that momentum = mv
3. What acceleration will be caused when a 35 N force is applied to a 20-kg object? You’ll have to come up with the equation on your own here!
