### 130 m
Explanation
## Step 1: Identify the components of the initial velocity### The initial speed is
at an angle of
. We need to find the vertical component of the initial velocity using
.## Step 2: Calculate the vertical component of the initial velocity### Using
.## Step 3: Use the kinematic equation to find the maximum height### The kinematic equation for vertical motion is
, where
at the maximum height. Solving for
, we get
.## Step 4: Substitute the known values into the equation###
.## Step 5: Round to the nearest option### The closest option to
is
.
