1) A scooter accelerates at 4.2 m/s2 from rest. How fast is the scooter moving after 3.0 seconds?
2) A soccer ball accelerates from rest and rolls 6.5m down a hill for 3.1 seconds. It is then stopped by a tree. Find final velocity.
This is for physics and I have several more problems like these if someone's interested, i'll post them as well.
