Were is conflicting testimony in a court
case. a police officer claims that his
radar monitor indicated that a car
was traveling at 1766 kmin (llomi/h).
the driver argues that the rodar must have
recorded the relative velocity because
he was only going 88km/h (55mi/h).
is it possible that both are telling
the truth? could ondbelying? prepore
scripts for expert witnesses, for both
the prosecution and the datensc, that
use physics to justify their positions
before the jury. create visual aids to
be used as tvidence to support the
different arguments.

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
