Given : value of the height, h m, in the diagram at which the tennis ball must be hit so that it will just pass over the net and land 6 metres away from the base of the net.
To Find : With what scale factor 0.9 m is to be multiplied to get the value of ‘ h’
Solution:
These are similar triangle
Hence
6 /(6 + 12) = 0.9/h
=> 6/18 = 0.9/h
=> 1/3 = 0.9/h
=> h = 0.9 x 3
Hence 0.9m must be multiplied with scale factor 3 to get real value of h
=> h = 2.7
Real value of h = 2.7 m
