The total distance travelled is km. The net displacement is km. displacement at t=18 hrs is km The distance between points E and F is km. The displacement between points E and F is km

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 wod

One of the fastest known animals is the Indian spine-tailed swift. A swift flies 2.80 km due north in a time of 32.8 s. a. What is its average velocity due north in meters per second? Enter a positive value if the average velocity is due north and enter a negative value if it is due south. answer in m/s b. What is its average velocity due north in miles per hour?

The speed limit for highway is typically 70 mph in MD. What is 70 mph in terms of m/s? 1.000 mile = 1609 m

1) A race car travels around a circular race track for which the start line and finish line are at the same location.   If the race is 888km long and the radius of the track is 1.414km, how many times did the car go around the track?  The race takes 2 hours and 45 minutes, what is the race car’s average velocity (in m/s) over the entire race?  What is the race car’s average speed (in m/s) over the entire race?

1. A pilot flies in a straight path for 1 h 30 min. She then makes a course correction, heading 10 degrees to the right of her original course, and flies 2 h in the new direction. If she maintains a constant speed of 610 mi/h, how far is she from her starting position?Your answer is    mi;Enter your answer rounded to two decimal places.   2. A steep mountain is inclined 74 degree to the horizontal and rises to a height of 3400 ft above the surrounding plain. A cable car is to be installed running to the top of the mountain from a point 880 ft out in the plain from the base of the mountain. Find the shortest length of cable needed.Your answer is    ft

v(m/s) The opposite figure shows the relationship between speed and 3 time. an object is in motion, the distance traveled by the object t(s) during (6s) in meters is equal to: 3 6

A suspicious-looking man runs as fast as he can along a moving sidewalk from one end to the other, taking 2.90 s. Then security agents appear, and the man runs as fast as he can back along the sidewalk to his starting point, taking 10.5 s. What is the ratio of the man's running speed to the sidewalk's speed? Number i Units

The record for a marathon is two hours, six minutes, 21 seconds. The marathon distance is 41.72 km. determine the average speed in m/s of a runner achieving this record.

The distance between two telephone poles is 44.0 m. When a 1.00-kg bird lands on the telephone wire midway between the poles, the wire sags 0.180 m. Draw a free-body diagram of the bird. How much tension does the bird produce in the wire? Ignore the weight of the wire.
