During a baseball game, a baseball is struck at ground level by a batter. The ball leaves the baseball bat with an initial speed v0 = 43 m/s at an angle θ = 15° 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.  Find the ball’s maximum vertical height hmax in meters above the ground.  Enter an expression in terms of v0, θ, and g for the time tmax it takes the ball to travel to its maximum vertical height.  Calculate the horizontal distance xmax in meters that the ball has traveled when it returns to ground level.

Question

During a baseball game, a baseball is struck at ground level by a batter. The ball leaves the baseball bat with an initial speed v0 = 43 m/s at an angle θ = 15° 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.

 Find the ball’s maximum vertical height hmax in meters above the ground. 

Enter an expression in terms of v0θ, and g for the time tmax it takes the ball to travel to its maximum vertical height. 

Calculate the horizontal distance xmax in meters that the ball has traveled when it returns to ground level. 


The image illustrates the trajectory of a projectile launched from a horizontal surface. Key elements of the diagram include:

- A ball represented at the starting point on the surface, which suggests the initial position of the projectile.
- The trajectory is depicted as a curved, dashed line showing the parabolic path the projectile will follow under the influence of gravity, indicating that it rises and then falls.
- A red arrow labeled "V" represents the initial velocity vector of the projectile. This arrow is inclined at an angle.
- The angle \(\theta\) is shown between the initial velocity vector and the horizontal axis, indicating the angle of projection.
- The horizontal axis is labeled as \(x\) and the vertical axis is labeled as \(y\), defining the coordinate system for analyzing projectile motion.
