(64 meter/day) x (1 kilometer / 1,000 meters) x (1 day / 24 hours) =
(64 x 1 x 1) / (1,000 x 24) (kilometer/hour) =
1/375 km/hour
(0.002667 km/hour, rounded)
2-2/3 meters/hour
(8-ft 9-inches) per hour
Let , speed of bowling ball is v .
Time taken by ball to hit the pins , 
.
Speed of sound , u = 343 m/s .
Time taken by sound to reach ear , 
.
Now ,
Time taken by sound to hear after release :
Hence , this is the required solution .
Acceleration can be any change in speed, increasing or decreasing.
You haven't said whether the ball is speeding up or slowing down.
If its acceleration is positive ... speed is increasing ... then in 2.5 seconds,
it GAINS (0.5 m/s² x 2.5 sec) = 2.5 m/s of speed. Added to its initial
speed of 2.0 m/s, it ends up moving at 4.5 m/s.
If its acceleration is negative ... speed is decreasing ... then in 2.5 seconds,
it LOSES (0.5 m/s² x 2.5 sec) = 2.5 m/s of speed. Added to its initial
speed of 2.0 m/s, it ends up moving at -0.5 m/s. That means that it ends up
moving in the opposite direction compared to its direction at the beginning of
the change.

Answer:
Newton's second law
Explanation:
The relationship between mass and acceleration is described in Newton's Second Law of Motion. His Second Law states that the more mass an object has, more force is necessary for it to accelerate.
