Question

4sin cube x -3sinx=4(√3÷2) cube -3(√3÷2)​

Answer 1

Answer:

Find the horizontal distance covered by a stone that falls from a 100 m mountain and hits a rock halfway down, as shown in the figure. Assuming the rock has no initial speed, do this for the following two scenarios:

(a) The stone hits the rock and is ejected at a 45 degree angle.

(b) The stone hits the rock and is ejected with such an angle that it reaches the maximum possible horizontal distance.

In both cases, assume that the stone is ejected with the same speed it had when hitting the rock.
