Question

When the sun is directly overhead, a hawk dives toward the ground with a constant velocity of 5.35 m/s at 52.0° below the horizontal. Calculate the speed of its shadow on the level ground. M/s?

Answer 1

Speed of Hawk's shadow on the level ground = 3.29 m/s

Step-by-step explanation:

When the sun is directly above the head of hawk shadow will be directly below hawk. So the speed of hawk's shadow will be equal to speed of hawk's in X -direction.

Velocity of hawk = 5.35 m/s

Angle from horizontal = 52.00⁰

Horizontal component = 5.35 cos 52.00⁰ = 3.29 m/s

So speed of hawk's shadow = 3.29 m/s
