Aball is thrown from an initial height of 3 ft with an initial upward velocity of 27ft/s the balls height h (in feet) after t seconds is given by the following. h=3+27t-16t^2. find all values of t for which the balls height is 13 ft.

t = 0.55 s and t = 1.14 s

Explanation:

as we know that height in terms of time is given as

now we have to find the time at which its height is h = 13 ft

so here we can say

so it will be at h = 13 ft height at t = 0.55 s and t = 1.14 s

answer: good job it's all correct !

explanation:

thermal energy is the answer
