Answer:

$Velocity = 70mph$

Step-by-step explanation:

Given

$Train = 50mph$

$Ball = 20mph$

Required

How fast is the ball seem to be moving?

This question illustrates relative velocity;

Since the ball and the train moves in the same direction, the required velocity relative to the person standing behind is:

$Velocity = Train + Ball$

i.e. we add both velocities

$Velocity = 50mph + 20mph$

$Velocity = 70mph$

Katen [24]

Answer:

The height of the lighthouse is $742.5\ ft$

Step-by-step explanation:

Let

h -----> the height of the lighthouse

we know that

The tangent of angle of 68 degrees is equal to divide the height of the lighthouse by the horizontal distance from the buoy to the base of lighthouse

$tan(68\°)=\frac{h}{300}$

Solve for h

$h=(300)tan(68\°)=742.5\ ft$
