Find the acceleration of this car when it is speeding up

Reference no: EM13523886

According to recent test data, an automobile travels 0.250 mi in 19.9 s, starting from rest. The same car, when braking from 60.0 mi/h on dry pavement, stops in 146 ft. Assume constant acceleration in each part of the motion, but not necessarily the same acceleration when slowing down as when speeding up.

Part A Find the acceleration of this car when it is speeding up.

Part B Find the acceleration of this car when it is braking.

Part C If its acceleration is constant, how fast (in mi/h ) should this car be traveling after 0.250 mi of acceleration? The actual measured speed is 70.0 mi/h; what does this tell you about the motion?

Part D How long does it take this car to stop while braking from 60.0 mi/h?
