Question

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 when its 112 ft above the
ground on the way down?

F. How long is the baseball in the air?

Answer #1

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?

if a ball is thrown vertically upward with a velocity of 95
ft/s, then its height after t seconds is
s=95t-19t^2
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?

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...

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
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...

An object is thrown vertically upward from a platform 80 feet
above the ground with a velocity of 64 feet per second. Given the
fact that the acceleration due to gravity is approximately -32
ft/sec/sec,
a) use antidifferentiation to determine the ‘velocity’, v(t), and
‘position above the ground’, s(t), functions; use these functions
to determine: b) when the object reaches its highest point; c) what
the highest point above the ground is; d) when it hits the ground;
e) the...

7. Suppose that a golf ball is thrown vertically with an initial
velocity of 40 meters per second. Answer the following questions
given that the ball’s height (in meters) after t seconds is
represented by the function ℎ(t)= −4.9t2 + 40t. Use
appropriate units for full credit. [15 points]
a. How long will it take for the ball to hit the ground?
b. What will the ball’s instantaneous velocity at t = 5
seconds?
c. Use your answer to (b)...

A ball is thrown vertically upward from the 40-ft level in an
elevator shaft with an initial velocity (straight up) of 50 ft/sec.
At the same instant, far below, an open-platform elevator passes
the 10-ft level in the elevator shaft, moving upward with a
constant velocity of 5 ft/sec. Determine (a) when and where the
ball will hit the elevator, (b) the relative velocity of the ball
with respect to the elevator when the ball hits the elevator.

A flare is launched upward with an initial velocity of 80 ft/sec
from a height of 224 ft. Its height in feet
after t seconds is given by h t t t ( ) = − + + 16 80 224. 2 How
long will it take the flare to reach the ground?

A ball is thrown vertically upward with a speed of
36.0 m/s.
a) How high does it rise?
b) How long does it take to reach its highest
point?
c) How long does the ball take to hit the ground after
it reaches its highest point?
d) What is its velocity when it returns to the level
from which it started?
