A Honda Fit (mass = 1000 kg) and a Volvo XC40 Recharge (mass = 2000 kg) are both going 15 m/s when they see the light ahead turn red, so the drivers must bring the vehicles to a stop. They both do so by applying a steady braking force to slow down smoothly. (a) If they each come to a stop in the same amount of time, is the braking force the same for both or is one greater than the other? Explain how you know in terms of momentum transfer. (b) Let's say the driver of the Fit takes 4.0s to slow to a stop. What distance will they have traveled during those four seconds? (c) Assuming that the driver of the XC40 uses exactly the same average braking force as the driver of the Fit, how long will it take them to slow to a stop? And what distance will they have traveled during that time?
