While driving to work one day, I was holding my coffee mug in my left
hand while changing the radio station with my right hand. Then my cell
phone rang, so I placed the mug on the flat part of my dashboard.
Then, believe it or not, a deer ran out of the woods and onto the road
right in front of me. Fortunately, my reaction time was zero, and I was
able to stop from a speed of 17 m/s in a mere 50 m, just barely
avoiding the deer, without the coffee mug sliding. The mug (with
coffee) had a mass of 550 g, and the mass of the deer was 150 kg.
Part A
What is the minimum possible value of the coefficient of static friction between the mug and the dashboard?

Georgia, standing on the back of the pick-up truck, wants to throw her last piece of balut to her mortal enemy, Emma. before the truck started moving, the two women are separated by a distance of 2 m. For two seconds, the truck uniformly accelerated until it reached a velocity of 4 m/s which it then maintained. With hatred, Georgia throws the last piece of balut with a velocity of 12.5 m/s at an angle of 40° from horizontal, measured relative to the truck. If she makes the throw 2.8 seconds after the truck started moving, will she be able to hit Emma?
Note that Emma is at rest due to exhaustion from their earlier fight and she cannot dodge the balut. Set your origin at point A. Neglect air resistance.
Two fan carts are on parallel inclined tracks are facing opposite directions. At t=0, the carts are
2.88 m apart with the fans on and they are both given a sharp push toward each other against
the direction the fans are pushing them. Cart A begins (after the push) with a speed of 1.35 m/s
to the right and has an acceleration of 0.44 m/s? to the left. Cart B begins (after the push) with a
speed of 1.05 m/s to the left and has an acceleration to the right of 0.52 m/s?. (Hint: Keep your
positive and negative directions consistent for both carts.)

Your job is to determine the relative speed of the collision, to help establish new crash standards. The faster train's "black box" shows that it began negatively accelerating at 2.1 m/s2m/s2 when it was 52 mm from the slower train, while the slower train continued at constant speed.

The dairy company has run out of bungee cords, so the crate is not tied down. You have been told to drive carefully because the coefficient of static friction between the crate and the bed of the truck is 0.600. You are not worried, because you are traveling on a road that appears perfectly straight. Due to your confidence and inattention, your speed has crept upward to 46.6 mi/h. Suddenly, you see a curve ahead with a warning sign saying, "Danger: unbanked curve with radius of curvature 35.0 m." You are 15.0 m from the beginning of the curve. What can you do to save the eggs?arrow_forward
