What else can I help you with?
If you have 3 balls on the top of a building and one is dropped. one is thrown downward. and one is thrown up and then goes downward Which has the fastest volocity when it hits the ground?
The thrown ball will (usually) have the highest velocity as the acceleration (resultant of force) used to throw it exceeds that of the other two balls. The ball thrown upward will have a higher downward velocity than the dropped ball even though their accelerations (due to gravity) are the same, as it has more time to travel downward. Although, If the ball thrown upward is thrown high enough, it may even travel faster than the ball thrown downward if the downward throw's force is not enough to beat the ball's terminal velocity (quite a bit of height would be required though).
Why a ball flies high when it is thrown upwards?
because of gravity and force. what goes up must go down. it also depends on how hard you throw the ball.
What is a walk in softball?
a walk is when you get 4 balls (when the ball is thrown to high or to low and the batter doesn't swing at it, it is a ball) and get to go to at least 1st base, you can steal the other bases.(just because it's called a 'walk' doesn't mean you get to walk, still run)
How aeroplane fly?
aeroplane have aerofoil shape (you could find in the internet how does it looks like)wings that have a specific shape that would make it fly. The high velocity at the top of aerofoil will create the low pressure and the low velocity below the aerofoil will create high pressure. thus, the high pressure will push the aeroplane upwards.
How high does the bounciest ball bounce?
The bounciest balls are the so-called bouncy balls, made of compressed synthetic rubber. These balls have an unusually high coefficient of restitution (inverse momentum) that allows them to return to up to 92% of a dropped height, and to utilize thrown force to reach extraordinary heights. Another generic name for the balls is "super balls," originally a trademark name for a 1964 invention first sold by the Wham-O toy company in 1966.
When did High Velocity Bowling happen?
High Velocity Bowling happened in 2007.
How is the word thrown used in sentence?
The ball was thrown high into the air.
Why do super balls bounce so high?
Super balls are made from a material called vulcanized rubber, which is highly elastic and can store and release a lot of kinetic energy upon impact. This elasticity allows the super ball to deform and then quickly return to its original shape, which propels it back upwards with considerable force, resulting in a high bounce.
What is the difference between high velocity and low velocity?
Velocity means speed. So high velocity is high speed and low velocity is low speed. Example: High velocity 204 Ruger 32 grains 4000 fps 1200 ft. lbs. Low velocity 577 Nitro Express 750 grains 2050 fps 7000 ft. lbs.
When was High Velocity Bowling created?
High Velocity Bowling was created on 2007-12-07.
Does high velocity affect rate of change of velocity?
Yes, high velocity can affect the rate of change of velocity. If an object is already moving at a high velocity, it may require more time or force to change its velocity compared to an object moving at a lower velocity due to inertia.
What is the impact velocity of a rock thrown horizontaly from a cilff?
The impact velocity of a rock thrown horizontal from a cliff depends on two things, the initial speed of the rock (vi) and the height of the cliff (h). The final velocity (impact velocity) is represented by vfFor this formula, air resistance is neglected, and acceleration due to gravity is assumed to be 9.8 m/s2. The acceleration is positive here because down is being treated as the positive direction. You will get the same result if you use negative 9.8 m/s2 and make the height negative. sqr() means square root.vf = sqr(19.6h + vi2)For example if the rock was thrown off a 3 meter high cliff at 20 m/s, the impact velocity would be sqr(19.6 x 3 + 202), which would be sqr(58.8 + 202), which would be 21.42 m/s.The angle relative to the ground is the inverse tangent of sqr(19.6h)/viwhich in this case is tan-1( sqr(19.6 x 3)/20), which is tan-1(7.67/20) which is 21.0 degrees.
