If a ball is thrown upward at 64 ft/sec at an initial height of 80 ft, how would you get the position function that finds the height as a function of t? Do you just integrate?
Thanks

What are you proposing to integrate?courtrigrad said:If a ball is thrown upward at 64 ft/sec at an initial height of 80 ft, how would you get the position function that finds the height as a function of t? Do you just integrate?
A position function is a mathematical equation that describes the position of an object at any given time. In the context of calculating projectile height, the position function is used to determine the height of the object at different points in time by plugging in the time value into the equation.
The initial height and velocity of a projectile can be determined by using the given information, such as the launch angle, launch height, and initial velocity. These values can then be plugged into the appropriate equations, such as the kinematic equations, to solve for the initial height and velocity.
Yes, the position function can be used for any type of projectile motion, as long as the motion is in a vertical direction and the acceleration due to gravity remains constant. This includes objects thrown horizontally, dropped from a height, or launched at an angle.
Air resistance can affect the accuracy of calculating projectile height by reducing the maximum height and increasing the time of flight. This is because air resistance acts as a resistive force, slowing down the projectile's motion and reducing its height. However, for smaller objects and short distances, the effect of air resistance is usually negligible and can be ignored in calculations.
Yes, there is a maximum height that a projectile can reach, also known as the vertical displacement. This is dependent on the initial velocity, launch angle, and acceleration due to gravity. In a vacuum, the maximum height can be calculated using the equation h = (v2sin2θ)/2g, where h is the maximum height, v is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity. In reality, air resistance may affect the maximum height and make it slightly lower than the calculated value.
