In fighting forest fires, airplanes work in support of ground crewsby dropping water on the fires. a pilot is practicing by dropping acanister of red dye, hoping to hit a target on the ground below. ifthe plane is flying in a horizontal path 90.0 m above the ground and with a speed of69.0 m/s (153 mi/h), at what horizontal distance from thetarget should the pilot release the canister?

The of a machine determines its "usefulness." a. input force b. output force c. mechanical advantage

Iwill give brainliest if you answer right : )

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
