Suppose you take a 3-hour trip in your car. For the first hour, you travel at a speed of 60 mi/hr. The weather suddenly gets very bad so that for the remaining 2 hours you travel at a speed of only 30 mi/hr. What was your average speed for the full three-hour trip?

You are driving along Lawrence Ave. at 60 km/h. You see the traffic light ahead is still green and decide
to speed up to try to make it through the intersection before it turns red (poor decision!). Your car
accelerates at 1.3 m/s?. You reach the light after accelerating for 4.3 seconds. What is your speed at
the light in m/s?

- An object has an acceleration that is directed opposite of its motion. What is true of the object? O It is moving in a circle. O It is slowing down. O It is moving at a constant speed. O It is speeding up. O It is moving vertically. 6 7 4.arrow_forwardAn aircraft performs a maneuver called an "aileron roll." During this maneuver, the plane turns like a screw as it maintains a straight flight path, which sets the wings in circular motion. If it takes it 21 s to complete the circle and the wingspan of the plane is 10.6 m, what is the acceleration of the wing tip? Express your answer in m/s².arrow_forwardIf an airplane is flying at 140 miles per hour East and turns in a smooth curve with a diameter of 3 miles till its headed West at the same speed, what is its average acceleration in m/s2 during the time it took to make the turn?

- I am driving at 35 mph on a foggy day when I see a car 5 miles ahead of me stopped in the road with its hazard lights on. I can accelerate my car at about -12 mph/s. How long do I have to decide if I will need to swerve to avoid hitting the car? Which is the correct equation to usearrow_forwardWhen visiting a friend in Atlanta you decide to drive around the city. You turn a corner and are driving up a steep hill. Suddenly, a small boy runs out on the street chasing a ball. You slam on the brakes and skid to a stop leaving a 50-foot-long skid mark on the street. The boy calmly walks away but a policemen watching from the sidewalk walks over and gives you a speeding ticket. He points out that the speed limit on this street is 25mph. After you recover your wits, you begin to examine the situation. You determine that the street makes an angle of 25◦ with the horizontal and that the coefficient of static friction between your tires and the street is 0.80. You also find that the coefficient of kinetic friction between your tires and the street is 0.60. Your car’s information book tells you that the mass of your car is 1600 kg. You weigh 140 lbs. Will you fight the ticket in court? Please draw a figure with your detailed answer.arrow_forwardWhen visiting a friend in Atlanta you decide to drive around the city.
