How far can you projectile vomit?
Projectile vomiting can come on suddenly, without any signs that it’s about to happen. Projectile vomit is expelled with much more force than regular vomit. It’s even been recorded to reach a distance of 1.2 meters, or almost four feet.
What happens when the projectile reach the maximum height?
Maximum height of the object is the highest vertical position along its trajectory. The object is flying upwards before reaching the highest point – and it’s falling after that point. It means that at the highest point of projectile motion, the vertical velocity is equal to 0 (Vy = 0).
At what angle height is maximum in projectile?
The textbooks say that the maximum range for projectile motion (with no air resistance) is 45 degrees.
How do you find the maximum height of a projectile motion problem?
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.
How far does vomit spray?
Experiments revealed that splashes and droplets produced during an episode of projectile vomiting can travel great distances (>3 m forward spread and 2.6 m lateral spread).
How far do sneezes and vomit travel?
One episode of projectile vomiting can contaminate close to 84 square feet, and virus particles can also be suspended in the air. This research reveals that germs are easily spread and may linger in places that appear to be clean.
What happens to the acceleration of a projectile when it reaches the maximum height Why?
At a projectile’s highest point, its velocity is zero. At a projectile’s highest point, its acceleration is zero.
When a projectile reaches maximum height what happens to its velocity and acceleration?
Before the object reaches the maximum height, the vertical speed v y v_y vyv, start subscript, y, end subscript of a projectile decreases, because acceleration is in the opposite direction. The direction of the velocity is initially upward, since the object’s height is increasing (see Figure 3 below).
At what time does a projectile reach its maximum height?
Determine how high the projectile traveled above its initial height by using the following formula where V is the initial vertical velocity and T is the time it takes to reach its peak: Height = V * T +1/2 * -32.2 ft/s^2 *T^2 For example, if you had an initial vertical velocity of 32.14 ft/s and a time of one second.
How fast is a sneeze in mph?
100 mph
Sprays can be a little difficult to track, but some enterprising scientists have managed to make a rough estimate. A cough can travel as fast as 50 mph and expel almost 3,000 droplets in just one go. Sneezes win though—they can travel up to 100 mph and create upwards of 100,000 droplets. Yikes!
When a ball is thrown vertically upwards at maximum height?
Hint: When a ball is thrown upwards with a certain velocity, the ball moves against the acceleration due to gravity and attains a maximum height. At the point of maximum height, the velocity of the ball is zero.
When an object was thrown upwards reaches its highest point which is true?
When an object is thrown upwards, it reaches the highest point, and at the highest point velocity of the object is zero.
When a ball is thrown vertically upward at the maximum height?
When a ball is thrown vertically upwards with velocity v0, it reaches a maximum height of h. If one wishes to triple the maximum height then the ball should be thrown with velocity.
When a projectile object reaches its maximum height the acceleration?
Question: A ball thrown vertically upward reaches a maximum height of 30 meters above the surface of Earth. At its maximum height, the speed of the ball is: Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero….Objects Launched Upward.
| Variable | Value |
|---|---|
| a | -9.8 m/s2 |
| t | 0.40 s |
What is the maximum height reached by the firework before it ignites?
Note also that the maximum height depends only on the vertical component of the initial velocity, so that any projectile with a 67.6 m/s initial vertical component of velocity will reach a maximum height of 233 m (neglecting air resistance).
