- Bill and Amy want to ride their bikes from their neighborhood to school which is 21.3 kilometers away. It takes Amy 38 minutes to arrive at school. Bill arrives 23 minutes after Amy. (Add Amy's time with 23 min to get Bill's time.) How much faster (in meters/second) is Amy’s average speed for the entire trip? m/s (Convert km to m and min to sec)The equation for the motion of an object with constant acceleration is d= do + vt + at, where d is distance from a given point in meters, do is the initial distance from the starting point in meters, v is the starting velocity in meters per second, a is acceleration in meters per second squared, and t is time in seconds. A car is stopped at a traffic light. When the light turns green, the driver begins to drive, accelerating at a constant rate of 4 meters squared. A bus is traveling at a speed of 15 meters per second in another lane. The bus is 7 meters behind the car as it begins to accelerate. per second Find when the bus passes the car, when the car passes the bus, and how far each has traveled each time they pass one another. it lad wodSpeed (km/h) Time (s) 0.0 0 10 20 30 40 50 60 70 80 12.

- Can you please answer this question and show all the stepsB. The graph at the right shows the journey of a car over a 50-second time interval. Find the car’s displacement after 50 seconds.NASA has fired a rocket straight up into the air from ground level with an unknown initial velocity. It reaches a maximum height of 164,000 feet. This happened in Cape Canaveral therefore the rocket is under the acceleration of Earth's gavity in which we all know is -32 ft/sec/sec. Please round your answers to two decimal places. a). Find the time it takes for the rocket to reach maximum height. b). find the initial velocity necessary to reach that height.
