The maximum height attaine by a
projectile is increased by 10% by increasing its speed of projecton
, without changing the angle of projection. …
What will be the net effect on maximum height of a projectile?
Maximum height will increase to
3 times that of initial
.
What affects maximum height?
The maximum height of the object is the highest vertical position along its trajectory. The maximum height of the projectile depends on the
initial velocity v
0
, the launch angle θ, and the acceleration due to gravity
.
Does speed affect maximum height?
Just like the case of the time of flight, we see that maximum height reached by the projectile
depends on both initial speed and the angle of projection (θ)
. Greater the initial velocity and greater the angle of projection from horizontal direction, greater is the height attained by the projectile.
What happens when an object reaches max height?
The instantaneous speed of any projectile at its maximum height is zero. Because gravity provides the same acceleration to the ball on the way up (slowing it down) as on the way down (speeding it up), the time to reach maximum altitude is the
same as the time to return to its launch position
.
Is the maximum height attained by projectile largest when its horizontal range is maximum?
No, horizontal range is maximum when θ = 45o and maximum height attained by projectile is largest when
θ = 90o
.
How do you describe the range covered by the projectile?
The range of the projectile is
the displacement in the horizontal direction
. There is no acceleration in this direction since gravity only acts vertically. … Like time of flight and maximum height, the range of the projectile is a function of initial speed.
What is the maximum height equation?
h = v 0 y 2 2 g
. This equation defines the maximum height of a projectile above its launch position and it depends only on the vertical component of the initial velocity.
What is formula of height?
How to Calculate Height By Geometry. … So, “
H/S = h/s
.” For example, if s=1 meter, h=0.5 meter and S=20 meters, then H=10 meters, the height of the object.
How long does it take the ball to reach its maximum height?
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.
What is the best angle for maximum height and air time?
As mentioned above, the sine function reaches its biggest output value, 1, with an input angle of
90 degrees
, so we can see that for a sky-high punt θ = 90. That means that the best way to launch a high-altitude projectile is to send it flying at a 90-degree angle to the ground—straight up.
What is the maximum height of the ball?
The required maximum height of the ball is
208 feet
.
Is height a function of time?
A yo-yo moves straight up and down. Its height above the ground, as a function of time, is given by the
function
, where t is in seconds and H(t) is in inches.
When a ball is thrown up it reaches a maximum height?
A ball is thrown up, it reaches a maximum height anf then comes down. IF t_1 and t_2 (t_2 gt t_1) ar the time that the ball takes to be at a particular height then the time taken by the ball to reach the highest point is .
v=u+at
,wehave 0 = u + ( – g) T
or T= u /g = 1/2 g ( t_2- t_1) //g = 1/2 (t_2-t_1)`.
Why does the velocity of an object rising up decreases as it reaches its maximum height?
Since gravity pulls the object toward the earth with
a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum height.
