Kinematic Equation which may help with this problem.

Answer 1

Distance, Velocity and Time

Formula:
`d=vt`

• d = distance
• v = velocity
• t = time

Solving the Question

We're given:

• v = 2.0 m/s
• d = 4.0 m
• Solve for t

`d=vt\\\\t=(d)/(v)`

⇒ Plug in the given values:

`t=(4.0)/(2.0)\\\\t=2.0`

Answer

Therefore, it took 2.0 seconds for the ball to reach the second player.
