Chapter 13.3, Problem 13.146P
At an intersection, car B was traveling south and car A was traveling 30° north of east when they slammed into each other. Upon investigation, it was found that after the crash the two cars got stuck and skidded off at an angle of 10° north of east. Each driver claimed that he was going at the speed limit of 50 km/h and that he tried to slow down but couldn’t avoid the crash because the other driver was going a lot faster. Knowing that the masses of cars A and B were 1500 kg and 1200 kg, respectively, determine (a) which car was going faster. (b) the speed of the faster of the two cars if the slower car was traveling at the speed limit.

1. At an intersection car A was traveling south and car B was traveling 35° north of east when they
slammed into each other. Upon investigation it was found that after the crash the two cars got stuck and
skidded off at an angle of 15° north of east. Each driver claimed that he was going at the speed limit of 60
km/h and that he tried to slow down but couldn't avoid the crash because the other driver was going a lot
faster. Knowing that the masses of cars A and B were 1000 kg and 1200 kg, respectively, determine (a)
which car was going faster, (b) the speed of the faster of the two cars if the slower car was traveling at the
speed limit.

This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
A motorist starts from rest at Point A on a circular entrance ramp when t = 0, increases the speed of her automobile at a constant rate and enters the highway at Point B. Her speed continues to increase at the same rate until it reaches 85 km/h at Point C.
Determine the speed at Point B. (You must provide an answer before moving on to the next part.)
The speed at Point B is km/h.

A physics teacher performs three different collision experiments in class.He uses two dynamics carts on an aluminum (frictionless) track.The red cart has a mass of 0.486kg and moves to the right with a speed of 0.255m/s.The blue cart has a mass of 0.267kg and moves to the left with a speed of 0.495m/s.
a.In the first collision, the carts have Velcrostuck on the front of them. The carts stick to each other upon impact.Find the final velocity of the two carts after they have stuck together.
b.In the second collision, the impact is cushioned by magnets on the fronts of the carts. The magnets do not provide a perfectly elastic collision.After the carts bounce away from each other, the red cart moves to the left with a speed of 0.205m/s.Determine the final velocity of the blue cart.
c.In the third collision, the collision is cushioned by a hook’s law spring, which provides a perfectly elastic collision.
i.Determine the final velocity of each cartafter the spring recoils (after it compresses…
