Answer:
6.21 seconds
Step-by-step explanation:
The position function of a free-falling object is,

Where,
= initial height of the object,
= initial velocity of the object,
Here,


Hence, the height of the ball after t seconds,

When s(t) = 0,




∵ Time cannot be negative,
Hence, after 6.21 seconds the ball will reach the ground.
28/32 reduces to 7/8
42/48 reduces to 7/8
equivalent fractions are proportionate....so yes, they are proportionate
