Halliday, Resnick & Walker β Motion in Two and Three Dimensions: Problem 121
Gliding down to ground. At time t = 0, a hang glider is 7.5 m above level ground with a velocity of 8.0 m/s at an angle of 30Β° below the horizontal and a constant acceleration of 1.0 m/s^2 upward. (a) At what time t does the glider reach the ground? (b) How far horizontally has the glider traveled by then? (c) For the same initial conditions, what constant acceleration will cause the glider to reach the ground with zero speed (no motion)? Use unit-vector notation, with iΜ in the horizontal direction of travel and jΜ upward.
π Solution Approach
Given: 0, a, 7.5 m, 8.0 m, 1.0 m
Find: (a) At what time t does the glider reach the ground?; (b) How far horizontally has the glider traveled by then?; (c) For the same initial conditions
