Answer 1

Answer #1

When the sun is directly overhead, the projected shadow gives the horizontal position of the hawk.

The hawk is flying at a constant speed of

Which can be split into a horizontal component and a vertical component.

The horizontal component is parallel to the ground and it gives the speed of the shadow.

So the speed of the shadow,

On takeoff, an airplane climbs with a speed of 183 m/s at an angle of 32.5° above the horizontal. The speed and direction of the airplane constitute a vector quantity known as the velocity. The sun is shining directly overhead. How fast is the shadow of the plane moving along the ground? (That is, what is the magnitude of the horizontal component of the plane's velocity?)

The mass of a pigeon hawk is twice that of the pigeons it hunts. Suppose a pigeon is gliding north at a speed of ?P=18.9 m/s when a hawk swoops down, grabs the pigeon, and flies off, as shown in the figure. The hawk was flying north at a speed of ?H=37.0 m/s, at an angle ?=45∘ below the horizontal at the instant of the attack. What is the birds' final speed ?f just after the attack The mass of...

A projectile is fired from the ground level with an initial velocity that has a vertical component of 20 m/s and a horizontal component of 30 m/s. Find the range R. In the figure below, a constant external force P=160 N is applied to a 20.0 kg box, which is on a rough horizontal surface. While the force pushes the box a distance of 8.00 m, the speed changes from 0.500 m/s to 2.60 m/s. Find the work done by...
