Express your answer to two significant figures and include the appropriate units. Submit My Answers Give Up My Answers G.Up

Explanation / Answer

here,

height of the plane , h = 70 m

horizontal speed , u = 44 m/s

let the time taken by the weight to reach the target be t

using seccond equation of motion

h = u *t + 0.5 * g*t^2

70 = 0 + 0.5 *9.8 * t^2

t = 3.78 s

the distance of target , d = u *t

d = 44 * 3.78

d = 166.3 m

the distance from the target pilot should drop the weight is 166.3 m
