Answer:

c.The two balls will have the same speed.

Explanation:

When two balls green and blue both are moving with initial velocity 10m/s.

The green ball has been tossed upward and blue ball downwards.

Air resistance is negligible means there is no force which oppose the motion of balls.

When blue balls has been tossed downward then the blue ball will move under the gravity.

When green fall downward then the ball falls under the gravity because there is no air resistance.

Therefore, both balls move with acceleration due to gravity when they wil reach at ground.

Therefore, the velocity of both balls are same.

Hence, the two balls will have the same speed.

Option c is true.

If air resistance is negligible the two balls will have the same speed.

Air resistance on object in motion

The air resistance on object moving upwards or downwards act to slow the object down. This air resistance reduces the speed of motion of the object and increases the time taken for the object to travel.

In the absence of air resistance every object will move at equal speed and spend equal time to travel a given distance.

Thus, we can conclude that if air resistance is negligible the two balls will have the same speed.
