You are a stunt person in the latest action movie and need to drive a car off a cliff, parachute out to safety, and let the car freefall to the bottom of the cliff. you must leave the cliff at a specific speed, so the car lands on the target below. you start from rest, hit the gas, and accelerate at a constant rate of 11 m/s2 for 7.5 seconds, when you realize you are going too fast. you apply the brakes for 5 seconds, slowing your car down with a constant acceleration of -4.5 m/s2 . the car leaves the cliff traveling horizontally, you parachute out, and the car hits the target 30 meters below. how far from the cliff is the target?

An object resting on a table weighs 100 n. with what force is the object pushing on the table? with what force is the table pushing on the object? explain how you got your answer.

People with normal vision cannot focus their eyes underwater if they aren't wearing a face mask or goggles and there is water in contact with their eyes. in a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina. with the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 2.05cm in front of the eye.)
