Answer:

Step-by-step explanation:

1) \sf v_{f} =v_{i} +gt

       = 50 + (-9*8) *1

       = 50 - 9.8

       = 40.2 m/s

2) The acceleration of the ball at its maximum height equals to the force of gravity. -9.8 m/s²

3) The velocity at its top of the path:When the ball is thrown straight up, its velocity keeps on decreasing due the pull of gravity which pulls it towards the ground. So, the velocity at the top of its path is zero.

What does it mean for two fractions to be equivalent? For two ratios to be equivalent?
poizon [28]

Answer:

Equivalent fractions and ratios mean that when simplified, they are the same one fraction or ratio. see examples below.

Step-by-step explanation:

For example, the fraction 1/2 is the same as 2/4 or 15/30 because when you simplify them, they are still 1/2. Therefore they are equivalent.

For example, the ratio 1:2 is the same as 5:10 or 10:20 since when broken down they all come down to 1:2. Hence they are equivalent.

Hope this answers your question.
