17. Two rocks are thrown off a cliff at the same height. Rock A is thrown horizontally at 0 degrees with a velocity of 14 m/s and lands 45m from the base. Rock B is dropped straight down from
the outside edge of the cliff.
If both rocks were released simultaneously, which one should strike the ground first?

A-Depends on height of cliff
B-Rock A
C-Rock B
D-They will strike the ground at the same time

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
