Answer:
Part a)

Part b)

Explanation:
Part a)
mass of the Falcon bird is given as

initial speed of the bird is

final speed of the bird is given as
(opposite direction)
So here the impulse given by falcon bird is given as



now the final momentum of Raven bird in perpendicular direction is given as



now the change in the angle of the raven bird is given as



Part b)
Final speed of the raven bird is given as



A scrap heap magnet can move Ferrous metals, so any metals containing Iron, stainless steel, steel etc.
And it cannot move anything that is not magnetic
(I hoped this helped ;) And good luck!)
Answer:
The minimum diameter of the stick to bear the normal stress as 100 psi is 0.1785 in.
Explanation:
Taking moment along point A

Also normal stress is given as 100 psi
Now

The minimum diameter of the stick to bear the normal stress as 100 psi is 0.1785 in.
Answer:
V = 20 m/s
Explanation:
Given the following data;
Mass = 80kg
Kinetic energy = 16,000 joules
To find the velocity;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;

Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the formula, we have;
16000 = ½*80*V²
16000 = 40V²
V² = 16000/40
V² = 400
Taking the square root of both sides, we have;
V = 20 m/s
So basically the objects would be sandpaper and smooth metal, the sandpaper can indirectly touch the metal since it’s so smooth and it won’t cause any temp change either
