A soccer ball is kicked horizontally off a 22.0-meter high hill and lands a distance of 35.0 meters from the edge of the hill.

Predict the time required for the pool ball to fall to the ground and the horizontal distance between the table's edge and the ball's landing location.

A pool ball leaves a 0.60-meter high table with an initial horizontal velocity of 2.4 m/s.

Predictable unknowns include the initial speed of the projectile, the initial height of the projectile, the time of flight, and the horizontal distance of the projectile. The two types of problems are: Problem Type 1:Ī projectile is launched with an initial horizontal velocity from an elevated position and follows a parabolic path to the ground. While the general principles are the same for each type of problem, the approach will vary due to the fact the problems differ in terms of their initial conditions. There are two basic types of projectile problems that we will discuss in this course. In a typical physics class, the predictive ability of the principles and formulas are most often demonstrated in word story problems known as projectile problems.

Combining the two allows one to make predictions concerning the motion of a projectile.

The mathematical formulas that are used are commonly referred to as kinematic equations. The physical principles that must be applied are those discussed previously in Lesson 2. In the case of projectiles, a student of physics can use information about the initial velocity and position of a projectile to predict such things as how much time the projectile is in the air and how far the projectile will go. Such predictions are made through the application of physical principles and mathematical formulas to a given set of initial conditions. One of the powers of physics is its ability to use physics principles to make predictions about the final outcome of a moving object.
