Textbook Question
Chapter 1, Problem 70AP
A woman wishing to know the height of a mountain measures the angle of elevation of the mountaintop as 12.0°. After walking 1.00 km closer to the mountain on level ground, she finds the angle to be 14.0°. (a) Draw a picture of the problem, neglecting the height of the woman’s eyes above the ground. Hint: Use two triangles. (b) Using the symbol y to represent the mountain height and the symbol x to represent the woman’s original distance from the mountain, label the picture. (c) Using the labeled picture, write two trigonometric equations relating the two selected variables. (d) Find the height y.

1.5 ms, and t₁ = 2 ms. From this curve, determine the following.
There are many well-documented cases of people surviving falls from heights greater than 20.0 m. In one such case, a 55.0 kg woman survived a fall from a 10th floor balcony, 29.0 m above the ground, onto the garden below, where the soil had been turned in preparation for planting.
Because of the "give" in the soil, which the woman compressed a distance of 15.0 cm upon impact, she survived the fall and was only briefly hospitalized.
(a) Ignoring air resistance, what was her impact speed with the ground (in m/s)?
m/s
(b) What was the magnitude of her deceleration during the impact in terms of g?
g
(c) Assuming a constant acceleration, what was the time interval (in s) during which the soil brought her to a stop?
S
(d) What was the magnitude of the impulse (in N⚫ s) felt by the woman during impact?
N⚫s
(e) What was the magnitude of the average force (in N) felt by the woman during impact?
N
Example
Two charges, one with +10 μC of charge, and
another with - 7.0 μC of charge are placed in
line with each other and held at a fixed distance
of 0.45 m. Where can you put a 3rd charge of +5
μC, so that the net force on the 3rd charge is
zero?
