Concept explainers
For Problems 121-124, use the following discussion.
Projectile Motion The path of a projectile fired at an inclination to the horizontal with initial speed is a parabola (see the figure).
The range of the projectile, that is, the horizontal distance that the projectile travels, is found by using the function
where feet per second per second meters per second per second is the acceleration due to gravity. The maximum height of the projectile is given by the function
In Problems 121-124, find the range and maximum height . (See the discussion on the previous page.)
The projectile is fired at an angle of to the horizontal with an initial speed of 150 meters per second.
