Automobile A starts from O and accelerates at the constant rate of 0.9 m/s². A short time later it is passed by bus B which is traveling in the opposite direction at a constant speed of 6 m/s. Knowing that bus B passes point O 20 s after automobile A started from there, determine when and where the vehicles passed each other. B BO

- Problem 4: A police car traveling at 95 km/h is traveling west, chasing a motorist traveling at 80 km/h (both velocities are with respect to the ground and are constant). Find: 1. The velocity of the motorist with respect to the police car. 2. If they are originally 250 m apart, in what time interval (in seconds) will the police car overtake the motorist.On the Apollo 14 mission to the moon, astronaut Alan Shepard 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 36 ⁰⁰ above the horizontal. A) How long was the ball in flight? B) How far did it travel? C) Ignoring air resistance, how much farther would it travel on the moon than on earth?Runner A is initially 9.0 mi west of a flagpole and is running with a constant velocity of 2.0 mi/h due east. Runner B is initially 1.0 mi east of the flagpole and is running with a constant velocity of 6.0 mi/h due west. How far are the runners from the flagpole when they meet? ?mi
- KACTICE ANOTHER Near the end of a marathon race, the first two runners are separated by a distance of 45.0 m. The front runner has a velocity of 3.50 m/s, and the second a velocity of 4.20 m/s. (a) What is the velocity of the second runner relative to the first? m/s faster than the front runner. (b) If the front runner is 250 m from the finish line, who will win the race, assuming they run at constant velocity? O The first runner will win. O The second runner will win. (c) What distance ahead will the winner be when she crosses the finish line? m Additional Materials Reading ASK YOUR TEACHER PRACTICE ANOTHE MY NOTEScan you please help me really quick!! thank you i need it in less than 10 minutesHow long after Car B started the race will Car B catch up with Car A?

- You threw a ball at 25 o from X axis, and it has initial velocity Vo = 15 m/s. Find out what are its X and Y velocities initially and finallyA billiard ball was set in motion on a counter by your mischievous little cousin who wanted the ball to hit your foot. To avoid your attention he set the ball in motion with a slow speed of 1.0 m/s (how did he know this unit?!) from a counter that is 1.1 m tall. Fortunately he missed. How long did it take to hit the floor?QUESTION 15 If the velocity of an object is zero at some point, then its acceleration must also be zero at that point. O True O False QUESTION 16 Suppose that an object travels from one point in space to another. Make a comparison between the magnitude of the displacement and the distance traveled by this object O A. The magnitude of the displacement can be either greater than, smaller than, or equal to the distance traveled. O B. The magnitude of the displacement is either less than or equal to the distance traveled OC The magnitude of the displacement is always equal to the distance traveled. O D. The magnitude of the displacement is either greater than or equal to the distance traveled.
