A surveyor measures the distance across a river that flows straight north by the following method. Starting directly across from a tree on the opposite bank, the surveyor walks a distance d = 122 m along the river to establish a baseline. She then sights across to the tree and reads that the angle from the baseline to the tree is θ = 40.5 degrees.

Calculate the momentum of the 2000.0-kg elephant charging the hunter at a speed of 7.50 m/s. Calculate the ratio of the elephant’s momentum to the momentum of a 0.0400-kg tranquilizer dart fired at a speed of 600 m/s. What is the momentum of the 90.0-kg hunter running at 7.40 m/s after missing the elephant?

Show that the variance of a Ber(p) trial is exactly $p(1-p)$, and use this to explain why any Bernoulli trial has a standard deviation of at most 0.50. Then use the central limit theorem to explain why, when flipping 100 fair coins in a row, it's pretty unlikely to see 70 or more heads.

3.5-6 A solid circular bar of diameter $d = 50$ mm (see figure) is twisted in a testing machine until the applied torque reaches the value $T = 500 \text{ N} \cdot \text{m}$. At this value of torque, a strain gage oriented at $45^\circ$ to the axis of the bar gives a reading $\varepsilon = 339 \times 10^{-6}$. What is the shear modulus $G$ of the material?
