Answer:
t = (f - v)/a
Step-by-step explanation:
We have been given that;
The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a, over time, t.
The question requires us to solve for t;
The first step is to subtract v on both sides of the equation,
f - v = v + at - v
f - v = at
The next step is to divide both sides by a,
(f - v)/a = t
which is our required equation solved for t.

Answer:
y= -1/2x +1
Step-by-step explanation:

The distance from the lighthouse to the boat will be given by:
tan θ=opposite/adjacent
θ=angle of depression=23
opposite= height of the lighthouse
adjacent=distance from the boat to the bottom of the light house
hence
tan 23=210/a
thus solving for a we obtain:
a=210/tan23
hence
a=494.73 ft
