All the equations you need are in my previous post

Use them and you will get the right units. I did part (b) first since it could be done in one step.
A 109 kg fullback runs at the line of scrimmage.
(a) Find the constant force that must be exerted on him to bring him to rest in a distance of 1.1 m in a time interval of 0.22 s.
(b) How fast was he running initially?
someone answered this earlier but i do not understand how you got your answers since once needs to be in Newtons (part a) and the other in m/s (part b) Thanks!
