Ajet - powered car called the spirit of america required 9600meters to stop from its highest speed . if the car decelerated at a rate of -2.0m/s , what was the initial speed of the car

A15,000 kg rocket traveling at +230 m/s turns on its engines. over a 6.0 s period it burns 1,000 kg of fuel. an observer on the ground measures the velocity of the expelled gases to be −1,200 m/s.

Acar traveling at a constant speed of 22.0 m/s passes a trooper hidden behind a billboard. one second after the speeding car passes the billboard, the trooper sets off in chase with a constant acceleration of 3.50 m/s2. how long does it take the trooper to overtake the speeding car? solve this problem by a graphical method. on the same graph, plot position versus time for the car and the trooper.

The focal length of a lens is determined by the curve of the lens and the material that the lens is made from. (5 points) is this true or false? ?
