1. The problem statement, all variables and given/known data
A 1.2*10power of 4 kg truck is travelling South as 22m/s
A)what net force is required to bring the truck to a stop in 330m
B)what is the cause of this net force

2. Relevant equations
Fnet=ma



3. The attempt at a solution
m=1.2*10power of 4 kg
Fnet=ma
= 1.2*10power of 4 kg

Thats as far as i got

Hint: try considering work and energy.
 
you know the trucks initial energy, right? What concept refers to change in energy?
