Question

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 reach its highest point?

c. What is the height of the stone at the highest point?

d. When does the stone strike the ground?

e. With what speed does the stone strike the ground?

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 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...

A stone is thrown vertically upward with a speed of 15.0 m/s
from the edge of a cliff 75.0 m high.How much later does it reach
the bottom of the cliff?What is its speed just before hitting?What
total distance did it travel?

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?

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...

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 stone is thrown from the edge of a cliff 350 ft above the
ground with a speed of 20 ft/s and an angle of 38° above horizon.
How long will it take the stone to reach the ground? And what is
the speed of the stone in impact? (Hint:g ≈ 32 ft/ s^2)

A
stone is thrown from the top of a cliff with the initial velocity
of 20.0 m/s straight upward. The cliff is 50.0 m high and the stone
just misses the edge of the cliff on its way down. Determine (a)
the time needed for the stone to reach its maximum height; (b) the
maximum height, as measured from the ground; (c) the time needed
for the stone to return to the level of the thrower; (d) the
velocity of...

A ball is thrown directly upward from the edge of a
rock and travels such that after t seconds its height in feet above
the ground is given by the equation s(t) =-2.5t^2+10t+2
1.Find the equation that represents the instant
velocity v(t) of the ball on t time.
2.When does the ball has zero velocity?
3. What is the maximum height that the ball
reaches?
4. When does the ball touches the surface of the
Earth?
5. build the graph...
