Suppose the pamot is flying north at 18.1 m/s, when the harpy eagle swoops down, grabs the parrot, and flies off. At the instant right before the pti attack, the harpy eagle is flying toward the parrot at an angle 8 39.1 below the horizontal, and a speed of 40.5 m/s Homework (soln after due Policies: deduct MC) What is the speed of the harpy eagle immediately after it catches its prey? You can check your answers he d date. You can keep trying to answer each question until you get it right or give up 40.5 m of What is the magnitu of the ang measured from 8.1 m horizontal, at which the harpy eagle is flying answer in your question for each incorrect immediately after the strike? For multiple-choice questions, the penalty depends on the number of choices available. eTextbook O Help With This Topic O Web Help & Videos E Previous Check Answer Copyright 20 2015 Sapling 52 privacy policy tact 3:12 PM /3/2015Explanation / Answer
m1 =2m2 =m ,
u1 = 40.5 cos (39.1)i -40.5sin(39.1)j
u1 = 31.43 i-25.54 j
u1x = 31.43i, u1y = -25.54 j
u2x = 18.1 m/s u2y =0
From conservation of momentum along x -axis
m1u1x+m2u2x =(m1+m2)v1x
2m(31.43)+m (18.1) =(2m+m)v1x
v1x = 26.99 m/s
From conservation of momentum along y -axis
m1u1y+m2u2y =(m1+m2)v1y
2m(-25.54) +0 =(2m+m)v1y
v1y = -17.03 m/s
v = [(26.99)+(-17.03)]^1/2
v = 31.9 m/s
Tan(theta) = -17.03/26.99
Theta =32.250
Direction is 32.250 below the horizontal
