A 2290 kg car traveling at 11.7 m/s collides with a 2620 kg car that is initially at rest at the stoplight. The cars stick together and move 3.30 m before friction causes them to stop. Determine the coefficient of kinetic friction betwen the cars and the road, assuming that the negative acceleration is constant and that all wheels on both cars lock at the time of impact.

A 1,4-kg object traveling at 5,5 m/s collides head-on with a
3-kg object traveling in the opposite direction at 3,9 m/s. If the
collision is perfectly elastic, what is the final speed of the
1,4-kg object? Answer in two decimal places. The answer is supposed
to be 7,32. Why is that?

As shown below, a 840 kg car traveling east collides
with a 1730 kg pickup truck that is traveling north. The two
vehicles stick together as a result of the collision. After the
collision, the wreckage is sliding at vf = 19 m/s in the
direction θ = 25° east of north. Calculate the speed of
each vehicle before the collision. The collision occurs during a
heavy rainstorm so you can ignore friction forces between the
vehicles and the wet...
