A. what is maximum height reached by the ball?

B. what is the velocity of the ball if its 114 ft above the ground on the way up?

C. what is the velocity of the ball when it is 114 above the ground on its way down?

Answer #1

if a baseball is thrown vertically upward with an initial
velocity of 128 ft/sec, the ball’s height after t seconds is
s(t)=128t-16t^2
A. Find the baseball's velocity and acceleration at time
t.
B. How long does it take the baseball to reach its highest
point?
C. How high does the baseball go?
D. What is the velocity of the ball when it is 112 ft above
the ground on the wh down?
E. What is the speed of the ball...

A ball is thrown vertically upward from a height of 5 ft with an
initial velocity of 83 ft/s. The distance s (in feet) of the ball
from the ground after t seconds is s = s(t) = 5 + 83t − 16t^2. (a)
What is the velocity v, in feet per second, of the ball after 2
seconds?
(b) When, in seconds, will the ball reach its maximum height?
(Round your answer to one decimal place.)
(c) What is...

If a ball is thrown upward with a velocity of 64 ft/sec, then
its height after t seconds is s=64t-16t^2. When does the ball reach
its maximum height?

A ball is thrown vertically upward from the edge of a cliff,
with an upward velocity of 20 m/s. On its way back down, it just
misses the end of the cliff.
(a) Find the position and velocity of the ball 1 s and 4 s
after it is thrown;
(b) Find the velocity of the ball when it is 5 m above the
flat surface of the cliff. Write the magnitude of the velocity in
the Answer box below...

A
ball is thrown directly upward from a height of 3 ft with an
initial velocity of 20 ft/sec. the function s(t) = -16t^2+20t+3
gives the height of the ball, in feet, t seconds after it has been
thrown. Determine the time at which the ball reaches its maximum
height and find the maximum height.

A ball is thrown vertically upwards with an initial velocity of
10 m/s, from a platform that is at a height of 75 m above the
ground. The ball reaches a maximum height and, on the way down,
misses the platform and falls all the way to the ground. Take the
magnitude of the acceleration due to gravity to be 10 m/s2.
(a) What is the velocity of the ball just before it reaches the
ground?
(b) How many seconds...

A
stone thrown vertically on Mars. Suppose a stone is thrown
vertically upward from the edge of a cliff on Mars (where the
acceleration due to gravity is only about 12 ft/s^2) with an
initial velocity of 64 ft/s from a height of 192 ft above the
ground. The height S of the stone above the ground after t seconds
is given by s=-6t^2+64t+192
a. Determine the velocity v of the stone after t seconds
b. When does the stone...

A blue ball is thrown upward with an initial speed of 21.2 m/s,
from a height of 0.5 meters above the ground. 2.6 seconds after the
blue ball is thrown, a red ball is thrown down with an initial
speed of 11.7 m/s from a height of 25.7 meters above the ground.
The force of gravity due to the earth results in the balls each
having a constant downward acceleration of 9.81
m/s2.
A) What is the speed of the...

17) A ball is thrown vertically upward from ground level with an
initial velocity of 96 feet per second. Use ?(?) = −32 ??⁄ 2.
