A Meteorite shooting vertically down into the Earth, weighing 27 pounds and traveling at 130 m/s, is found 22 cm deep in the ground. What was the magnitude of the acceleration necessary to stop the meteorite? ?
Homework Answers
here,
intial speed , u = 130 m/s
s = 0.22 m
let the accelration be a
v^2 - u^2 = 2 * a * s
0 - 130^2 = 2 * a * 0.22
solving for a
a = 3.84 * 10^4 m/s^2
the magnitude of accelration is 3.84 * 10^4 m/s^2

A car is 162 m from a stop sign and traveling toward the sign at 27 m/s. At this time, the driver suddenly realizes that she must stop the car. If it takes 0.200 s for the driver to apply the brakes, what must be the magnitude of the constant acceleration of the car after the brakes are applied so that the car will come to rest at the stop sign?

The rolling resistance of steel is typically mu_r = .002. If a train weighing 160,000 kg is rolling at 12m/s and the engineer turns off the engine to let the train cruise to a stop, how much time will it take to come to a stop? How far will the train move during this time? What is the drag force on a 1.5 m wide, 1.8 m high car traveling at 20 m/s? A 22 cm diameter bowling ball has...
