Question

A projectile whose vertical movement is a y(t) - 16t^2 + 224t + 1,920 feet on the ground of t seconds of being thrown. a) When is the projectile speed equal to zero? b) What is the maximum height?

Answer #1

let the equation F(16) = -16t^2 + 128t +25 represent the height
in feet of a ball thrown vertically upward at time t seconds
a) find the instantaneous velocity of the ball at t = 2
seconds
b) find the impact velocity of the ball

11. a ball is thrown up from the ground with an initial velocity
of 120 feet per second. The height s in feet can be expressed as a
function of time t in seconds by s(t)=85t-16t^2 a. when does the
ball reach its maximum height b. what is the maximum height c. when
does the ball hit the ground
12. a farmer has 2800 feet of fencing material with which to

answer to the nearest hundredth. a. When (i.e., how many seconds
after launch) will the projectile reach its maximum height?
_______________
b. How many seconds after launch will it take for the projectile to
return to earth?
_______________
c. What is the maximum height achieved by...

An object is launched upward from a platform so that its height
(in feet) above the ground t seconds after it is launched
is given by the function h(t)=-16t^2
+160t+176.
a. When does the object reach its maximum height? What is the
maximum height?
b. When does the object hit the ground?
c. What is the domain and range of this
function (given the context)?
d. Sketch an accurate graph of this function in an
appropriate window. Mark on your...

An object is thrown upward at a speed of 128 feet per second by
a machine from a height of 13 feet off the ground. The height (h)
of the object after (t) seconds can be found using the equation
h(t)=−16t2+128t+13
When will the height be 269 feet? and When will the object reach
the ground?

Two seconds after being projected from ground level, a
projectile is displaced 40 m horizontally and 53 m vertically above
its launch point. Its horizontal component of initial velocity is
v0x=20 m/s. Its vertical component of initial velocity
is v0y=36 m/s. At the instant the projectile reaches
maximum height above ground level, the displacement is x=74 m.
Answer questions a, b, and c below. Show all work and details.
Give explanation for your answer.
a) What is the horizontal range...

Application of Newton second Law of Motion to vertical movement
of a body using differential equation: A ball that weights 8 pounds
is thrown vertically downward toward the earth form a great height
with an initial velocity of 3ft/sec. As the ball falls, it equal to
four times the velocity of the ball (in ft/sec).
(a) What is the velocity of the ball at the end of t
seconds?
(b) How far has the ball fallen at the end of...

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 projectile is fired at an angle of 28 degrees above the
horizontal with an initial velocity of 1,800 feet per second from
an altitude of 1,000 feet above the ground.
A) Formulate the vector valued function (in simplified form) for
the position of the projectile at any time, t.
B) When and where (in terms of down range distance) does the
projectile strike the ground? Be clear and label your results,
including units.
C) When does the projectile reach...

a rock is thrown upward from a bridge into a river below. the
function f(t)=-16t2+32t+94 determines the height of the
rock above the surface of the water (in feet) in terms of the
number of seconds t since the rock was thrown.
(A) what is the bridges height above water?
(B) how many seconds after being thrown does the rock hit the
water?
(C) how many seconds after being thrown does the rock reach its
maximum height above the water?...
