Marty and Jennifer's twin granddaughters, Emma and Clara, are preternaturally talented at riding hoverboards. One fine day, the young twins, each riding her own hoverboard, are cruising across the hoverpark arm-in-arm. The mass of each twin is 27.50 kg kg (the mass of each skater includes the mass of her hoverboard). Suddenly, Clara spots an obstacle ahead; to save them both from collision with the obstacle, she gives Emma a two-handed horizontal push. As a result, Emma ends up traveling at 2.50 m/s m/s , due North, and Clara end up traveling at 5.10 m/s m/s , 31.0 degrees degrees North of East.

Part A) What was the original speed of Emma and Clara when they were traveling arm-in-arm?

Part B) In what direction were Emma and Clara originally traveling?

Give your answer as an angle in degrees measured CCW from due East (when looking Down); the size of the angle should be less than 180 degrees. If the angle would be larger than 180 degrees, instead measure CW from due East and give your answer as a negative angle.

Part C) How much kinetic energy was added to the Emma-Clara system by Clara's push?

One of the most successful attacks against wireless networks (WLAN) is the Evil Twin attack. The goal is to introduce an attacker-controlled wireless access point near the “known good” WLAN network. This access point will advertise the exact same SSID as the authorized WLAN. Wireless users may accidently connect to this malicious access point thinking it is part of their authorized network. Once the connection is established, the attacker can initiate a man-in-the-middle attack and capture or relay traffic while...

A retrospective study of 159 pairs of twins was performed. The twin pairs each had one male child and one female child. Their birth weights were studied to determine if the male twin was consistently heavier. The difference in weights was calculated by subtracting the female weight (in ounces) from the male weight (in ounces): d=xm-xf After looking at 159 pairs of twins, the study finds the 99% confidence interval for the mean difference of weights (in ounces) is: 2.4...
