The maximum height is negative
Did you know?
SpletAnswer (1 of 4): Height is the shortest distance and hence displacement away from earth or big mass that should be negative in vector terms. Height of an object with respect to the large mass can be increased or decreased with time. Height of humans grow by time in positive direction away from th... SpletNote that because up is positive, the initial velocity is positive, as is the maximum height, but the acceleration due to gravity is negative. Note also that the maximum height depends only on the vertical component of the initial velocity, so that any projectile with a 67.6 m/s initial vertical component of velocity will reach a maximum height ...
SpletWell, just from the definition of acceleration, change in velocity is equal to acceleration-- negative 9.8 meters per second squared-- times time, or times change in time. We're just talking about the first half of the ball's time in the air. So our change in time is 2.5 seconds-- times 2.5 seconds. SpletThe term -5 (x-4)^2 will always evaluate as a non-positive number. This is because (x-4)^2 will always be evaluated as a positive value (because the square of anything is positive) and any positive multiplied by -5 will be negative. The greatest value of h (x) then is when (x-4)^2 = 0, or when x=4. h (4) = -5 (4-4)^2 + 180 h (4) = -5 (0)^2 + 180
Splet$\begingroup$ Imagine you're in space and your ball has a little rocket engine. You throw the ball away, and the rocket engine is thrusting to return it to you. At the farthest point, before it reverses direction, it briefly stopped moving; but it's clear that the engine is continuously thrusting, accelerating toward you at the same rate. Splet18. maj 2024 · So the maximum height is achieved at time x = 5, which corresponds to a height of: y = ax² + bx + c = (1/2) (5)² - 5 (5) = -12.5 However, we are looking for the maximum height, so we take the absolute value of this result, which gives: y = 12.5 Therefore, the maximum height reached by the object is 12.5 feet.
