Thelma and Louise drive off a 1000 m tall cliff with initial velocity vo =(30 m/s, 0) (about 65 mi/hr in the +x direction). If I want to know how long a time they spend in
the air, which equation should I use?
(ufy)2 = (voy)2 + 2a, Ay
0 = to + vaxt + at
Oys = yo + voyt + zat?
O Vfy = Voy + ayt

Astone is dropped with no initial velocity from the top of a cliff and hits the ground a time of 3.9 s later. what is the height of the cliff, in units of meters? you may assume that air resistance is negligible. give the answer as a positive number question 15 a figure skater is rotating at a rate of 200 revolutions per minute. what is the angular speed, in units of rad/s? 200 o 20.9 12000 o 3.33

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road. (a) will your car hit the crate before the crate hits the road if you neither brake nor swerve? (b) during the fall, is the horizontal speed of the crate more than, less than, or the same as that of the truck?
