3. You drop an egg out of your 10 m 2nd story window. If it took 1.43 sec, calculate the
velocity right before the egg hits the ground.

4. You are walking at a speed of 1.5 m/sec. You see your friend up ahead 10 m in front of
you. Calculate how long it takes for you to reach your friend.

Suppose you increase your walking speed from 7 m/s to 13 m/s in a period of 2 s. what is your acceleration?
