A woman stands at a horizontal distance x from a mountain and measures the angle of elevation of the mountaintop above the horizontal as 𝜃. After walking a distance d closer to the mountain on level ground, she finds the angle to be 𝜑. Find a general equation for the height y of the mountain in terms of d, 𝜑, and 𝜃, neglecting the height of her eyes above the ground.

During a baseball game, a baseball is struck at ground level by a batter. The ball leaves the baseball bat with an initial velocity v0 = 46 m/s at an angle = 22° above horizontal. Let the origin of the Cartesian coordinate system be the ball's position the instant it leaves the bat. Air resistance may be ignored throughout this problem. 

Part (a) Express the magnitude of the ball's initial horizontal velocity v0x, in terms of v0 and

Part (b) Express the magnitude of the ball's initial vertical velocity voy in terms of v and .

Part (c) Find the ball's maximum vertical height hmax in meters above the ground. 

Part (d) Create an expression in terms of v0and for the time it takes tmax the ball to travel to its maximum vertical height.

Part(e) Calculate the horizontal distance xmax in meters the ball has travelled when returns to ground level

A physics student stands at the top of hill that has an elevation of 37 meters. He throws a rock and it goes up into the air and then falls back past him and lands on the ground below. The path of the rock can be modeled by the equation y = –0.02x² + 0.8x + 37 where x is the horizontal distance, in meters, from the starting point on the top of the hill and y is the height, in meters, of the rock above the ground. How far horizontally from its starting point will the rock land? Round your answer to the nearest hundredth
