Concept explainers
Physics A ball is thrown vertically upward with an initial velocity of 96 feet per second. The distance (in feet) of the ball from the ground after seconds is .
(a) At what time will the ball strike the ground?
(b) For what time is the ball more than 128 feet above the ground?
To find:
a. The time at which the ball strike the ground.
b. The time at which the ball is more than 128 feet above the ground.
Answer to Problem 34AYU
Solution:
a. After 6 seconds the ball will strike the ground.
b. For the time , the ball will be more than 128 feet above the ground level.
Explanation of Solution
Given:
The distance of the ball from the ground after seconds is given by:
Calculation:
a.
To find the time at which the ball will hit the ground is found by solving the equation:
Thus after 6 seconds the ball will strike the ground.
b. The ball is more than 128 feet above the ground level.
Thus for the time the ball will be more than 128 feet above the ground.
