Answer:
The maximum height reached by the golf ball when v = 35 is 24.5 meters.
Step-by-step explanation:
Given : A golf ball, thrown upwards, rises at a speed of v metres per second.
The ball reaches a maximum height of h metres. h is proportional to the square of v. When v = 20, h = 8.
To find : Work out the maximum height reached by the golf ball when v = 35 ?
Solution :
h is proportional to the square of v i.e.
Where, k is the constant of proportionality
When v = 20, h = 8,
The equation became .
Now, when v = 35 the value of h is
Therefore, the maximum height reached by the golf ball when v = 35 is 24.5 meters.
