Respuesta :
The time taken by second ball to land on the floor is 0.30 seconds.
What is the relation between speed, time and distance?
Speed is determined by dividing the distance covered by the time taken. Calculating the units for speed requires knowledge of the units for both time and distance. Since the distance is measured in metres (m) and the time is measured in seconds (s), the units in this example will be metres per second (m/s).
The answer can be calculated by the equation:
[tex]D = V \times T[/tex]
Where, V = speed, T = time, D = distance
So, for first ball the time is given to be 0.60 s and speed is given to be v.
We get equation,
[tex]D = 0.60v[/tex]
For second ball speed is given to 2v and the distance is same as first ball
We get equation,
[tex]D = T_2 2v[/tex]
Where, T₂ = Time taken by second ball
By both the equations of first and second ball. we get,
[tex]0.60v = T_2 2v[/tex]
[tex]T_2 = \frac{0.60}{2}[/tex]
[tex]T_2 = 0.30 s[/tex]
Therefore, the second ball will take 0.30 seconds to land on the floor.
