Problem 89

A 1400 kg car moving at 5.3 m/s is initially traveling north along the positive direction of a y axis. After completing a 90# right-hand turn in 4.6 s, the inattentive operator drives into a tree, which stops the car in 350 ms. In unit-vector notation, what is the impulse on the car (a) due to the turn and (b) due to the collision? What is the magnitude of the average force that acts on the car (c) during the turn and (d) during the collision? (e) What is the direction of the average force during the turn?

Step-by-Step Solution:
Step 1 of 3

NEWTON’S SECOND LAW ● an object’s change in motion (acceleration) is directly proportional to applied force ● an object’s change in motion (acceleration) is inversely proportional to the object’s mass ● mass is just a measure of inertia, an object’s stubbornness...
