Homework Statement


a 3000 kg truck traveling at a speed of 4.0 m/s makes a 90 degree turn in a time of 5.0 s and emerges from this turn with a speed of 7.0 m/s. what is the magnitude of the average resultant force on the truck during this turn?

The Attempt at a Solution


I think this might be a centripetal force problem but the change in velocities is messing me up.

What is force? F = m*a

What is acceleration? ΔV/Δt

So ... what is the ΔV ... keeping in mind that V is a vector?

You have the Δt conveniently given as 5 sec.
