A 6 kg truck moving at 6 m/s comes to a stop in 8 seconds. What are the steps to find the force exerted on the truck?

• You can solve for force using τ=Fr

• You have to solve for acceleration using a=Δv/t and then use F=ma

• It is impossible to solve for force

• You can immediately solve for force using F=ma

How do you find the resultant vector of two vectors that are perpendicular to each other?

• Use the Pythagorean Theorem

• It is impossible

• Subtract the magnitudes and keep the direction of the bigger vector

• Add the magnitudes and keep the direction
