A rogue SGA suggests a new Homecoming activity this year: sophomore launching. When it's your turn, you load your helmeted sophomore into the catapult certified to send the average-
sized person you chose across the gym at 35 m/s. It was hot in the gym, so Mr. Watts set up
two giant fans- one blowing toward 130° at 4 m/s and the other blowing toward 270° at 5
m/s. Standing at (-12, -8) you face the catapult 60° toward the empty back corner set the angle
of elevation to 22.5° and release the lever. If your sophomore is in the air for 1.7 s, where does
he hit the wall?

After the near spacecraft passed mathilde, on several occasions rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid eros, the final destination for the mission. after getting close to eros, further small adjustments made the momentum just right to give a circular orbit of radius 45 km (45 × 10^3 m) around the asteroid. so much propellant had been used that the final mass of the spacecraft while in circular orbit around eros was only 545 kg. the spacecraft took 1.04 days to make one complete circular orbit around eros. calculate what the mass of eros must be.

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.

Waves are used in many practical applications to support work, entertainment, and health. one example is the use of ultrasound imaging to safely track the development of a growing fetus. what is a specific example of a practical application of waves in medicine, entertainment, safety, or other fields? provide a brief explanation of how the properties of waves are useful to that application.
