Answer:
Depth = 7.06 m
Velocity = 11.77 ms-1
Step-by-step explanation:
We use the equation of motion:-
s = ut + 1/2 g where s = distance fallen , t = time , u = initial velocity and g = 9.81 ms^-2 , the acceleration due to gravity.
So s = 0(t) + 1/2 * 9.81 (1.2)^2
= 7.06 m to nearest tenth.
We use another equation of motion to find the final velocity:-
v^2 = u^2 + 2gs where v = final velocity
v^2 = 0 + 2*9.81 * 7.06
= 138.52
v = √138.52 = 11.77 m s-1
