What constant acceleration would a car, starting from rest, have to sustain in order to reach a velocity of 36 m/s due east in 3.0 s? a) 108.0 ms2 due east b) 12.0 ms2 due east c) 4.0 ms2 due east 324.0 ms2 due east

A train is traveling south at 58.4 m/s when the brakes are applied. It slows down with constant acceleration to a speed of 6.00 m/s in a time of 9.00 s.   How far does the train travel during the 9.00 s? If the displacement is toward north, enter a positive value. If the displacement is toward south, enter a negative value. answer in m

US Airways flight leaves Philadelphia in the early evening and arrives in Frankfurt 8.05 hours later. The airline distance from Philadelphia to Frankfurt is about 6.6 x 103 km, depending to some extent on the flight path followed. What is the average speed of the plane, in kilometers per hour? Average speed = total distance covered

The velocity-time leftward-moving table represents the motion of a car. What is the magnitude and direction of the car's acceleration? Time (s) 0.0 1.0 2.0 3.0 4.0 Magnitude: Direction: Velocity (m/s) 26.0, left 20.0, left 14.0, left 8.0, left 2.0, left

A vehicle is moving at +36.0 m/s when the driver sees a stop sign. In 2.60 seconds, the vehicle comes to a stop. 1) Find the vehicle’s acceleration (magnitude and direction). 2) Find the vehicle’s displacement (magnitude and direction).

1.) An acceleration of 90.0 m/s^2 was experienced by a rocket which was launched upward. The acceleration stopped after 10.0 seconds when it run out of fuel . What is the highest speed (m/s) that the rocket experienced?

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.
