Answer 1

To solve the physics problem, we use the principles of projectile motion to find the initial velocity and time to reach the green by breaking down the problem into horizontal and vertical components and solving simultaneously.

Step-by-step explanation:

To address this challenge problem, we need to apply the principles of projectile motion. We're looking for the initial velocity and time to reach the green for a golf ball hit from Hanglip Mountain.

First, let's break down the initial velocity into horizontal (vx) and vertical (vy) components:

• vx = v * cos(θ)
• vy = v * sin(θ)
  

Given:

• Horizontal distance (dx) = 359.0 m
• Height difference (dy) = 400.0 m
• Launch angle (θ) = 40°

To find the initial velocity (v), we use the formula for the horizontal motion. Since there's no acceleration horizontally,

• dx = vx * t

And for the vertical motion, using the formula dy = vy * t - 0.5 * g * t2, where g is the acceleration due to gravity (9.8 m/s2).

We solve these two equations simultaneously to find v and t.
