Aplane traveling horizontally at 120 m/s over flat ground at an elevation of 3610 m must drop an emergency packet on a target on the ground. the trajectory of the packet is given by xequals 120t, yequals minus4.9tsquaredplus3610, for tgreater than or equals 0, where the origin is the point on the ground directly beneath the plane at the moment of the release. how many horizontal meters before the target should the packet be released in order to hit the target? set up an equation involving t that could be solved in order to find out how long it takes the packet to reach the ground after being released.

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
