Quadratic Word Problems: Projectile Motion (page 1 of 3) Usually the object is moving straight up or straight down. An object is launched at 19.6 meters per second (m/s) from a 58.8-meter tall platform. The equation for the object's height s at time t seconds after launch is s (t) =

General Quadratic Word Problems (page 2 of 3) The height h is 4/3 the width, so h = (4/3) w. Then the area is A = hw = [ (4/3) w ] [ w] = (4/3) w2 = 192. I need to solve this "area" equation for the value of the width, and then back-solve to find the value of the height.

Problem 2. Working together and separately to complete a job. You get the quadratic equation. Apply the quadratic formula (see the lesson ) to solve this equation. The equation has two roots: and . The second root does not fit the given conditions: if Bill covers the roof in two days, then Andrew has 2-5=-3 days, which has no sense. So, the potentially correct solution is : Bill covers the roof in 15 days.

PROJECTILES - EXAMPLE 1PROJECTILES - EXAMPLE 2PROJECTILES - EXAMPLE 3A ball is shot from a cannon into the air with an upward velocity of 40 ft/sec. The equation that gives the height (h) of the ball at any time (t) is: h(t)= -16t2 + 40ft + 1.5. Find the maximum height attained by the ball's first take a minute to understand this problem and what it means. We know that a ball is being shot from a cannon. So, in your mind, imagine a cannon firing a ball. We know that the ball is going to shoot from the cannon, go into the air, and then fall to the ground..See more on algebra-class

Quadratic Equations are useful in many other areas: For a parabolic mirror, a reflecting telescope or a satellite dish, the shape is defined by a quadratic equation. Quadratic equations are also needed when studying lenses and curved mirrors.

More Word Problems Using Quadratic Equations Example 2 A manufacturer develops a formula to determine the demand for its product depending on the price in dollars. The formula is D = 2,000 + 100P - 6P 2 where P is the price per unit, and D is the number of units in demand. At what price will the demand drop to 1000 units? Show Step-by-step[PDF]

Quadratic Formula Word Problems 1. Jason jumped off of a cliff into the ocean in Acapulco while vacationing with some friends. His height as a function of time could be modeled by the function h(t) = −16 t2 +16 t + 480 , where t is the time in seconds and h is the height in feet.
