Explain using words and calculations!! 52Current Attempt in Progress A Boeing 747 "Jumbo Jet" has a length of 59.7 m. The runway on which the plane lands intersects another runway. The width of the intersection is 24.9 m. The plane decelerates through the intersection at a rate of 6.18 m/s2 and clears it with a final speed of 42.1 m/s. How much time is needed for the plane to clear the intersection?

From the coordinates obtained in Part B, find the slope of the position-time relationship for the bowling ball using the "rise over run" algorithm. ▸ View Available Hint(s) 2.5m 0.40m/s 2.5m/s ○ 0.40 sAn object is moving in the positive x-direction. Select all true statements considering its 1 dimensional motion. If it is increasing its speed, its acceleration is in the positive x-direction. If it is not accelerating, it will move at a constant rate. If it is decreasing its speed, its acceleration is in the negative x-direction. If it is increasing its speed, its acceleration must be constant. It can be slowing down and have an acceleration in the positive x- direction. If its acceleration is non-zero, it will move forward by equal amounts over equal time intervals.
