An airplane takes off as shown following a trajectory described by equation y=Kx2, where K=2×10−4 ft −1. When x=900 ft, the speed of the plane is VO=110mph. Using the component system shown. provide the expression for the velocity of the airplane when x =900ft. Express your answer in ft/s. (Round the final answers to four decimal places.) The expression for the velocity of the airplane is v=1 i^+j^)f(s
A package is pushed up an incline at x=0 with an initial speed v0. The incline is coated with a thin viscous layer so that the acceleration of the package is given by a=−(gsin(θ)+ηv). where g is the acceleration due to gravity, η is a constant, and v is the velocity of the package. If θ=30∘,v0=14.5ft/s, and η=8 s−1, determine the time it takes for the package to come to a stop. (Round the final answer to four decimal places.) The time taken for the package to come to a stop is S.
