An eagle is flying horizontally at a speed of 3.1 m/s when the fish in her talons wiggles loose and falls into the lake 5.8 m be
DedPeter [7]

Answer:11.101 m/s

Explanation:

Given

Velocity of eagle=3.1 m/s

Eagle is at height of 5.8 m

Fish is dropped with a horizontal velocity of 3.1 m/s

time taken by fish to reach lake is

h=ut+\frac{gt^2}{2}

here u=0 (vertical velocity)

5.8=\frac{9.8\times t^2}{2}

t=1.087 s

Vertical velocity acquired by fish is v=u+at

v=0+9.8\times 1.087=10.66 m/s

Horizontal velocity=3.1 m/s

Therefore net velocity=\sqrt{10.66^2+3.1^2}=11.101 m/s

tan\theta =\frac{v_y}{v_x}=\frac{10.66}{3.1}=3.43

\theta =73.74^{\circ} below horizontal

A box is at rest on a slope
matrenka [14]

Answer:

170 N

Explanation:

The following data were obtained from the question:

Mass (m) = 20 Kg

Angle (θ) = 30°

Acceleration due to gravity (g) = 9.8 m/s²

Weight (W) =?

The perpendicular component of the weight can be obtained by using the following formula:

W = mg × Cosθ

W = 20 × 9.8 × Cos 30

W = 196 × 0.866

W = 169.7 ≈ 170 N

Therefore, perpendicular component of the weight is 170 N
