Question
The driver of a 1024 kg truck traveling 32.6 m/s North on I-77 has to make a sudden stop. If it requires a distance of 57.1 m for the truck to stop, use conservation of energy to find the net force acting on the truck.
Answers
Force x distance = work done against friction = initial kinetic energy
Solve for the force
F = (1/2) M Vo^2/X
Solve for the force
F = (1/2) M Vo^2/X
