List out (calculate) the initial and final velocities, the initial and final momentums, the impulse, and the amount of force required for the change described to occur for the five listed situations: A car with a mass of 4.0 x 103 kg starts at rest and accelerates to 40 km/h in one minute (1). It then slams on its breaks and slows to 5 km/h in 5 seconds (2). It then comes to a complete stop in 1 second (3). Then it reverses to a speed of 7 km/h in 10 seconds (4). Lastly, it comes to a stop in 3 seconds (5).
