A 1000 kg car traveling 60° south from east at 30 m/s collides with
a 3000 kg truck traveling north at
20 m/s. The cars stick together after the collision.
a) Is the momentum of the tr uck conserved before and after the
collision? Why?
b) Is the momentum of the car and tr uck together conserved before
and after the collision?
Why?
c) Draw the velocity vector for the car before collision and write
down the x and y component of
the momentum,
d) Draw the velocity vector for the truck before collision and
write down the x and y component
of the momentum,
e) What is the magnitude and direction of velocity of the wreckage
after the collision? (notice
that they stick together after collision)
Hint: calculate the momentum of the wreckage at each direction, and
divide it by the total
mass.
f) If the friction coefficient for the wreckage sliding on the road
is 0.5, how long does it take
for the wreckage to stop?
Hint: Calculate the friction force on the wreckage, and its total
momemtum and use the
impulse formula to solve for the time.

Related T-Test Sample
1. A researcher is interested in testing whether rats learned a maze after daily training sessions. The researcher recorded the number of errors committed by each rat before any training in the maze. Then, the researcher recorded the number of errors made by each rat after training. The scores below summarize the errors by each rat before and after training. Perform a dependent-sample (repeated-measures) t-test on the scores to test whether or not the number of errors was lower after training than before training. Like virtually all real research, please use a two-tailed test. Using two or three sentences, describe the results of the experiment in APA format.
