A spider crawling across a table leaps onto a magazine blocking its path. The initial velocity of the spider is 0.860 m/s at an angle of 33.6° above the table, and it lands on the magazine 0.0790 s after leaving the table. Ignore air resistance. How thick is the magazine? Express your answer in millimeters.

A particle with charge q moves in a circular orbit around the origin with radius a in the xy-plane with constant angular velocity omega. At t = 0 the particle sits at the point (a, 0).
A 4020 kg roller coaster crests a 24 m high hill with negligible speed. The roller coaster loses 44 kJ of energy on the way down. Determine the speed of the roller coaster
A 1500 kg car carrying four 87kg people travels over a rough "washboard" dirt road with corrugations 4.40 m apart which causes the car to bounce on its spring suspension. The car bounces with maximum amplitude while its speed is 19km/h. The car now s..
