I got a different answer for #2
Answer:
19.29 m/s
Explanation:
Apply the conservation of linear momentum in north-south direction:
Apply the conservation of linear momentum in east-west direction:
Dividing the two equations:
Thus, the speed of the eagle immediately after it catches its prey is 19.29 m/s.
Answer:
8.05 m/s^2
Explanation:
Instantaneous angular speed(w) = 1.25 rad/s
Angular acceleration (α) = 0.745 rad/s^2
Distance from the centre to where the child is (r) = 4.65m
Tangential acceleration = αr
= 0.745 * 4.65
= 3.464 m/s^2
Centripetal acceleration = w^2r
= (1.25)^2(4.65)
= 7.266 m/s^2
Total acceleration = √3.464^2 + 7.266^2
= √64.794052
= 8.05m/s^2
Answer:
I think B is the answer of this question
