A stone is thrown vertically upward with a speed of 12 meters per second from the edge of a 70 m cliff How much later does it reach the bottom of the cliff?
H = H0 + V0 T + 1/2 G T2
H0 = 70 m
V0 = 12 m/s
G = -9.8 m/s2
We want to know ' T ' when H=0 .
0 = 70 + 12 T - 4.9 T2
T = -1/9.8 [ -12 ± sqrt(144 + 1,372) ] =
-1/9.8 [ -12 ± 38.9358 ] =
T = 5.1975 seconds(T = -2.7486 seconds is also a solution to the math but isn't physically relevant)

How fast is a stone moving when it reaches a height of 11 meters if it is vertically thrown upward with a speed of 18 meters per second?
v2 = u2 + 2as where v = current velocity, u = initial velocity, a = acceleration, and s = displacement. Taking a = - 9.8 ms-2 v2 = 182 - (9.8 x 11 x 2) = 108.4 v = 10.4 ms-1
How high does the stick go and What is the speed of the stick when it hits the ground if A stick held at a height of 2.50 meters is thrown into the air at 2.00 meters per second?
1000000 m
The velocity of a baseball 4 seconds after it is thrown vertically upward with a speed of 32.1 is?
If that's 32.1 meters per second initially, then after 4 seconds it's fallingwith a speed of 7.1 meters per second.If that's 32.1 feet per second initially, then it returns to the thrower's hand injust under 2 seconds, and it's in the dirt long before 4 seconds have passed.If it had been tossed at the edge of a cliff, then after 4 seconds, it would befalling with a speed of 96.7 feet per second.
How can a ball be thrown that it reaches the longest distance across vertically horizontally angled?
if the bal is thrown by making 45 degree angles. with the ground..it will travel maximum distance...
A ball is thrown horizontally from a cliff and hits the ground 4 seconds later 40 meters from the base of the cliff?
The ball was thrown horizontally at 10 meters per sec, and the thrower's arm was 78.4 meters above the base of the cliff.
How long does it take for a ball to hit the ground if it was thrown vertically atop a 2 meter building at 15 meters per second vertically?
The answer depends on whether the ball is thrown vertically upwards or downwards. That critical piece of information is not provided!
A ball is thrown horizontally from a cliff at a speed of 9 meters per second What is its speed one second later?
Ignoring air resistance, its horizontal speed is still 9 meters per second, its vertical speed is approx. 9.81 m/s, as the acceleration of gravity is 9.81 meters per second per second.
How fast will a ball thrown straight down go?
10 meters per second due to gravity
A ball is thrown horizontally from a cliff at a speed of 8 meters per second. What is its speed one second later?
After a second, the ball will still have a horizontal velocity of 8 meters per second. It will also have a vertical velocity of 9.8 meters per second (Earth's acceleration is about 9.8 meters per square second). The combined speed (using the Law of Pythagoras) is about 12.65 meters per second.
When will an object land if it is thrown straight from a building at 5 meters per second?
It depends on the height of the building and also on the direction the object is thrown in (up, down etc.).
What is the acceleration of an object thrown 3.5 meters at 44 meters per second?
The acceleration of an object thrown vertically upwards can be calculated using the kinematic equation (v_f^2 = v_i^2 + 2a \cdot d), where (v_f) is the final velocity, (v_i) is the initial velocity, (a) is the acceleration, and (d) is the distance. Given that the object is thrown vertically upwards, the equation becomes (0 = (44 , \text{m/s})^2 + 2 \cdot a \cdot (-3.5 , \text{m})). Solving for (a), we find that the acceleration is approximately -104 m/s², which indicates that the object is accelerating downwards.
What is the velocity of an object thrown vertically into the air at its highest point?
At the highest point, the velocity of an object thrown vertically into the air is momentarily zero as it changes direction. This is the point where it transitions from going upward to downward.
A body is thrown vertically upward What is the magnitude of its acceleration?
A projectile fired directly upwards has no positive velocity. Its only velocity is attributed to the force of gravity, which is -9.8 meters per second squared.
What is the furthest distance an object has been thrown by a human vertically and horizontally?
Horizontally
What angle a projectile thrown to achieve maximum vertically distance traveled?
90
