## Does the velocity of the cannon ball matter or will it hit the monkey at any velocity?

The bullet’s initial velocity, or the distance between hunter and monkey, is irrelevant to the final outcome and affects only the height above the ground where bullet meets monkey.

## Why did they move the bullet being dropped to 360 ft away?

They moved the bullet being dropped so that it would be at about the same location that the bullet being fired was going to land. 3. They determined that the two bullets hit the ground about 39 milliseconds apart, which is faster than humans can blink or even see at all.

## What agent exerts the centripetal force on the runner?

What is the centripetal acceleration of the runner, and what agent exerts force on the runner? = 25 m = 3.1 m/s², the frictional force of the track acting on the runner’s shoes exerts the force on the runner.

## What is the direction of the force that acts on the clothes spinning in a top load washing machine what exerts the force?

Centrifugal Force acts along the radius outwards and hence can be used to throw the water molecules on the clothes radially outwards during the spin cycle of the washing machine.

## What is the formula for initial velocity?

Let us take a quick look at those formulas. The first formula to find initial velocity is u = v – at.

## How do you find the final velocity of a projectile?

v x = v 0 cos θ 0 = ( 30 m / s ) cos 45 ° = 21.2 m / s . The final vertical velocity is given by (Figure): vy=v0y−gt. v y = v 0 y − g t .

## Can bullet fire if dropped?

For example, if you drop your cartridge near a steel object and it lands at the perfect angle with enough force, the bullet could go off. When there’s enough force, the impact on the primer would mimic the impact of a firing pin after the trigger of a gun is pulled.

## How fast can a bullet fall to earth?

It will then start falling and accelerate towards the ground under the influence of gravity until it reaches its terminal velocity, which is limited by air resistance. According to the US Centers for Disease Control and Prevention, falling bullets can hit the ground at speeds greater than 61 metres per second (m/s).

## What are the 3 main concepts of projectile motion?

Key Points: Range, Symmetry, Maximum Height. Projectile motion is a form of motion where an object moves in parabolic path. The path that the object follows is called its trajectory.

## Why does the faster ball not fall as far as the slower one?

The faster ball crosses home plate within the strike zone, but the slower ball is below the batter’s knees. Why does the faster ball not fall as far as the slower one? The faster ball is in the air a shorter time, and thus gains a smaller vertical velocity.

## What force causes centripetal force?

The frictional force supplies the centripetal force and is numerically equal to it. Centripetal force is perpendicular to velocity and causes uniform circular motion. The larger the Fc, the smaller the radius of curvature r and the sharper the curve.

## What force propels a runner forward?

The static friction force that the ground applies to the runner propels the runner forward, and is equal and opposite to the parallel force the runner applies to the ground. If there were no static friction force the runner will slip.

## What would happen if the cannonball velocity was very high?

If the speed is very high, it will leave Earth in a parabolic (at exactly escape velocity) or hyperbolic trajectory. (E) for example horizontal speed of approximately greater than 11,200 m/s for Earth.

## Why does the cannon ball go faster than the cannon?

The ball accelerates rapidly and the cannon recoils in the opposite direction, but with much less acceleration than the cannonball because the cannon is much heavier (Newton’s second law).

## What is the velocity of a cannon?

Weapon | Low velocity | High velocity |
---|---|---|

Artillery cannons | Less than 396 m/s (1,299 ft/s) | Between 910 and 1,070 m/s (3,000–3,500 ft/s) |

Tank guns | – | Between 470 and 1,020 m/s (1,550–3,350 ft/s) |

Small arms | – | Between 1,070 and 1,520 m/s (3,500–5,000 ft/s) |

## What is the average velocity of a cannonball?

Standard Civil War cannonball was 12 lbs (5.4 kg). The shot speed is 250 miles per hour (820 ft per second). The cannons wouldn’t be pointed vertically obviously but straight out of the sides of the ship, probably a 45 degree angle.
