a ball dropped vertically,falls d metres in t seconds.d is directly propotional to the square of t.the ball drops 125 metres in the first 5 seconds.how far does the ball drop in the next 9 seconds

Respuesta :

Answer: 405m

Step-by-step explanation: First, we'll need to divide 125 by the square of 5 (25) to find the constant (because d is directly proportional to the square of t). This gives us 5.

Then, we'll need to square 9, giving us 81.

Finally, to find d, we need to multiply 81 by our constant which we calculated earlier, which is 5. This gives us 405.
