You are in the car traveling down the road and suddenly a bike jumps out in front of you 50 ft away. Luckily your excellent anti-lock breaks stop the car in 20 ft. How far would you have needed to break if you had been going twice as fast?
I understand the answer is 80, but I don't understand how to properly use the equation:
v^2=vo^2+2aΔx
Could someone please explain what each piece of this equation means and how to utilize it for this type of question?

A car (m = 2000 kg) is traveling down a 15 degree incline at 65 m/s. The driver slams on the breaks causing the wheels to lock. Omega_x = 0.3. How far S will the tires skid on the road? If the driver can skid only 10 m before hitting another vehicle, how fast will the driver hit the other vehicle?

3) A sports car is speeding toward you down the road. The car is traveling at 25.2 meters per second and the exhaust produces sound waves with a frequency of 845 Hz. Find the observed frequency as the car is driving towards you and when the car is driving away from you. How do they compare? Would you notice the difference in the sounds? Use 343 m/s for the speed of sound.

A toy car of mass 0.35 kg travels along a circular banked road, with banking angle 30°. The circle has radius 0.80 m. Sarah wants to make the car move as fast as possible, but if it goes too fast, it slips off the road. Therefore, Sarah cuts a 0.80- meter piece of string, attaches one end to the car, and attaches the other end to a nail stuck in the center of the circle. Unfortunately, the string is thin...
You're driving down the highway late one night at 17m/s when a deer steps onto the road at 44m in front of you.
You're driving down the highway late one night at 17m/s when a deer steps onto the road at 44m in front of you. Your reaction time before stepping on the breaks is 0.50 s, and the maximum deceleration of your car is 12m/s^2.Part A asks how much the distance is between you and the deer when you come to a stop, which the answer was 23 meters.Part B is where I am stuck and it asks what the maximum speed...

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...

In fact, the low-fare airline referred to itself as a customer service company that just happened to fly planes. But on Valentine's Day 2007, JetBlue was hit by the perfect storm-literally-of events that led to an operational meltdown.
