What is the fastest speed at which a tennis ball can cross the net horizontally and still land in the court? From the net to the end line is 12 m, and the height of the net is 1 m. Neglect air resistance and spin on the ball. A. 0.04 m/s
B. 27 m/s
C. 53 m/s
D. 45 m/s

self note *6

B. 27 m/s

Explanation:

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.

the inner core.

good luck: )
