Question

A train travels along a horizontal circular
curve that has a radius of 200 m. If the speed
of the train is uniformly increased from 30
km/h to 45 km/h in 5s, determine the
magnitude of the acceleration at the instant
the speed of the train is 40 km/h.

NASA has fired a rocket straight up into the air from ground level with an unknown initial velocity. It reaches a maximum height of 164,000 feet. This happened in Cape Canaveral therefore the rocket is under the acceleration of Earth's gavity in which we all know is -32 ft/sec/sec. Please round your answers to two decimal places. a). Find the time it takes for the rocket to reach maximum height. b). find the initial velocity necessary to reach that height.
