I'm doing revision work from the beginning of the year and I can't find the formulas for these two questions. -
1) Calculate the velocity of the pellet before it strikes the putty
2) Calculate the average frictional force it takes for the car to come to rest if its traveling at 15ms and comes to a rest after 20m.
