Gi is standing on the top of a 275 feet building she throws a ball straight up into the air. the balls velocity is given as 48 ft/sec. the height, in feet, of the ball after t seconds is given by h=-16t^2+48t+275. a. how long will it take for the ball to reach its maximum height above the ground? b. what is the maximum height that the ball reaches? c. how many seconds does it take for the ball to finally hit the ground?

John is hitting baseballs. the height of the ball is given by y=-16x^2+25x+5 (x is seconds, y is height in feet) 1.) what is the original height of the ball hitting the bat? 2.) what is the maximum height that the ball reaches? 3.) how long does it take for the ball to reach its maximum height? 4.) when does the ball hit the ground? find the vertex of the parabola. 1.) k^2-56=k 2.) b^2+10b=-24 Physics, 14.09.2019 01:30, meeeekmill
Alead ball is shot from a cannon vertically upward with initial velocity of 44.0 m/s from ground level at the base of a 63.0 m high cliff. the ball reaches a maximum height above the top edge of the cliff and then falls downward, landing on the top edge of the cliff (treat this as a vertical one-dimensional problem). the cannon has negligible height, so assume the ball begins its vertical ascent at ground level. a) determine the time it takes for the lead ball to reach the maximum height of its trajectory? b) from ground level, determine the maximum height reached by the ball. c) what is the velocity and acceleration of the ball when it is at its maximum height? d) how much time elapses for the ball to fall from its maximum height to the top edge of the cliff? e) what is the velocity of the ball just before it lands on the top edge of the cliff?

Let =−++ denote the position of an object subject to a constant downward acceleration due to gravity (where is given approximately by / or 9.8m/, is the initial velocity and is the initial displacement. for this problem, a ball is thrown vertically upward from the ground with an initial velocity of 160 ft/sec. (a) when will the ball hit the ground? sec. (b) with what velocity will the ball hit the ground? ft/sec. (c) when will the ball reach its maximum height? sec.
Do you know the correct answer?
John bounces a ball off the ground, and it leaves the ground with a velocity of 10 m/s. how long wil...
