Thus the ball hits the ground after
2. 5 seconds
after reaching its highest point.
How long does it take the same ball to hit the ground after it reaches its highest point?
At its highest point,
the ball will have a positive displacement
, and will have a zero displacement when it returns to its starting point. If the ball isn’t caught, but continues toward the Earth past its starting point, it will have a negative displacement.
What happens when a ball reaches its highest point?
At its highest point,
the ball will have a positive displacement
, and will have a zero displacement when it returns to its starting point. If the ball isn’t caught, but continues toward the Earth past its starting point, it will have a negative displacement.
How long does the ball take to reach its highest point?
It takes
about 88 seconds
for the cannonball to reach its maximum height (ignoring air resistance). You have 176 seconds, or 2 minutes and 56 seconds, until the cannonball destroys the cannon that fired it.
How long in S does it take to reach its highest point?
It takes
15 seconds
to reach the highest point.
What is its acceleration when it reaches its highest point and is stopped at an instant?
When you throw a ball up in the air, its direction/velocity on the way up, although it rises up into the air, is actually downward. On its way up, its speed decreases, until it momentarily stops at the very top of the ball s motion. Its acceleration is
-9.8 m/s^2
at the very top.
Does it take longer for a ball to go up or down?
The answer is:
Down
. Only if there was no air resistance would the up and down times be the same.
How long does it take something to hit the ground?
Conclusion: The magnitude of the velocity of the ball is
26.3 m/s
for the parabolic motion just before it hits the ground and this greater than the 17.1 m/s for the velocity of the ball that falls straight downward.
How high will a ball go if it is thrown upward with a speed of 15 m s?
A ball is thrown up with a speed of 15 m/s . How high wiil it go before it begins to fall ? (g=9.8 m//s^(2) Please note that here the ball is going up against the gravity ,so the value of g is to be taken as negative . Thus the ball will go the a maximum height of
11.4 meters
before of begins to fall.
What is the height reached by the ball after 1 second?
After 1 second, the height of the ball is
86 feet
.
How long does it take the rock to reach half of its maximum height?
(d) How long does it take the rock to reach half its maximum height? The highest point is 180, so the half of it is 90. 2 ≈ 25.61. Answer:
4.39,25.61 sec
.
When a ball is thrown vertically upwards then at the highest point?
When a ball is thrown vertically upward, it continues upward until it reaches a certain position, and then it falls downward. At that highest point,
its velocity is instantaneously zero
.
When a ball is tossed vertically upward the time it takes to reach the highest point is?
We know the value of g in SI is 9.8 m/second square. So just for example, if a ball is thrown vertically upwards with 98 m/s velocity, then to reach the maximum height it will take = 98/
9.8 =10 seconds
.
What is the acceleration when it reaches its highest point?
At a projectile’s highest point, its
acceleration is zero
.
What it is acceleration just before it hits the ground?
So the acceleration of the projectile is equal to the acceleration due to gravity,
9.81 meters/second/second
, from just after its thrown, through its highest point, and until just before it hits the ground.
When we throw a ball upward what happens to its speed while it is going up?
When you throw a ball up in the air, its direction/velocity on the way up, although it rises up into the air, is actually downward. On its way up,
its speed decreases
, until it momentarily stops at the very top of the ball s motion. Its acceleration is -9.8 m/s^2 at the very top.
