A ranger wants to determine the height of a tree across a river. The angle of elevation from the bank is 43°. When she walks back from the bank 27 feet, she determines that the angle of elevation is 32°. How tall is the tree? Round your answer to the nearest foot. Enter your answer here:
A woman stands at a horizontal distance x from a mountain and measures the angle of elevation of the mountaintop above the horizontal as θ. After walking a distance d closer to the mountain on level ground, she finds the angle to be ϕ. Find a general equation for the height y of the mountain in terms of d, ϕ, and θ, neglecting the height of her eyes above the ground. y =
3. A ball, a solid sphere of radius r and mass m, is positioned at the top of a ramp that makes an angle of 0 with the horizontal. The initial position of the sphere is at a distance of d from its final position at the bottom of the incline. a) Find the velocity of the ball at the bottom of the ramp in terms of m, r, d, 8, and g. The moment of inertia of a sphere...
One hundred feet from the trunk of a tree on level ground, the angle of elevation of the top of the tree is 370. Estimate the height of the tree to the nearest foot.
An arrow is shot at an angle of θ=45∘ above the horizontal. The arrow hits a tree a horizontal distance D=220m away, at the same height above the ground as it was shot. Use g=9.8m/s2 for the magnitude of the acceleration due to gravity. Part A Find ta, the time that the arrow spends in the air. Part B How long after the arrow was shot should the apple be dropped, in order for the arrow to pierce the apple...
