Question
Two cars approach each other from an initial distance of 2400 m. Car A is moving to the east at a constant rate speed of 40 m/s. Car B is moving to the west at a speed of 10 m/s but is accelerating at a rate of 2.00 m/s2. What is:
a. the time before the cars meet
b. the distance A traveled before meeting C
c. the relative speed at which the cars hit

- Driving down the road at a speed of 23.9 m/s, you suddenly notice a fallen tree blocking the road a distance of 82.0 m ahead of you. You step on the brake pedal and decelerate at a constant rate. What must the magnitude of your acceleration be so that you will come to a stop 6.6 m in front of the tree? a. 3.79 m/s^2 b. 3.48 m/s^2 c. 3.22 m/s^2 d. 7.58 m/s^2arrow_forwarda. 0.400 m/s2b. 0.555 m/s2c. 0.308 m/s2d. 0.385 m/s2arrow_forwardIn an amusement-park ride, cars rolling along at high speed suddenly head up a long, straight ramp.

- A tennis-ball gun launches tennis balls at 18.5 m/s. It's pointed straight up and launches one ball; 2.0 s later, a second ball is launched. a. At what time( after the first launch) are the two balls at the same height? b. What is that height? c. What are both balls' velocities at that point?arrow_forwardI see that an object has is decelerating, what does this tell me about A? A. Nothing at all, what i see has nothing to do with A B. A is a positive C. A is a negative D. A could be either, depending on the direction of the velocity Can I do the vertical part of a projectile motion problem separately from the horizontal part? A. Always. Horizontal motion is completely separate from vertical motion though they share time B. Never. C.

- Two trains are 900.0 kilometers apart. One is in Portland. The other is in San Francisco. They both begin traveling toward each other at the same time. The Portland train travels with an average velocity of 80.0 km/hr South. The San Francisco train travels North with an average velocity of 65.0 km/hr North.a. At what time will the two trains meet?b. How far away will they be from Portland when they meet?arrow_forwardOn the Apollo 14 mission to the moon, astronaut Buzz Aldrin hit a golf ball with a golf club improvised from a tool. The free-fall acceleration on the moon is 1/6 of its value on earth. Suppose he hit the ball with a speed of 29 m/sm/s at an angle 22 ∘∘ above the horizontal. a. how long was the ball in flight in seconds? b. how far did it travel in meters? c.

You pass a second police car at 55 mph at 10:53 a.m., which is located 39 mi from the first police car. If the speed limit is 60 mph, can the police cite you for speeding? а. a. The total time between your two police car sightings was P hours. b. Your average speed between the two police car sightings was 8, mph. c. Can the police cite you for speeding? No, your average speed was less than the speed limit. CYes, since your average speed was more than the speed limit, there must have been somewhere within the 39 mi where you were driving more than 60 mph.arrow_forward
