Question

suppose a person standing on a tower of height 15(root 3 +1)m and observing a car coming towards the tower. he observed that angle of depression changes from 30o to 45o in 3 s.

find the speed of the car.

is it true that, if a car moves towards the the tower, the angle of elevation decreases ?

suppose if we interchange the angles of both the cars. will it be conceptually correct ?

which qualities should be associated with a person driving the car ??

Answer 1

(i) Speed of the car - see pic

(ii) No, if a car moves towards the tower the angle of elevation increases.

(iii) No, it will not be conceptually correct because of the above statement (ii)

(iv) Values should be associated - Cautious, Aware, Speed limitations, Rule
