How much time does it take a person to walk 12 km north at a velocity of 6.5 km?
1 hour, 50 minutes, 46.15 seconds
What is initial velocity?
Initial velocity is the original starting velocity. I love math! It makes you smart like a math smart person.
How long would it take for a person to walk 400m if their speed rate is 2 seconds per 8 m?
100 seconds
How far will a person fall in 10 seconds?
1,100 to 1,300 feet.
A 180 lb person jumps from 16 story building how fast do they fall?
32 feet per second per second is the standard acceleration.As the object accelerates (usually downwards due to gravity), the drag force acting on the object increases. At a particular speed, the drag force produced will be equal to the downward force, mostly the weight (mg), of the object. Eventually, it plummets at a constant speed called terminal velocity (also called settling velocity). Terminal velocity varies directly with the ratio of drag to weight. More drag means a lower terminal velocity, while increased weight means a higher terminal velocity. An object moving downward at greater than terminal velocity (for example because it was affected by a force downward or it fell from a thinner part of the atmosphere or it changed shape) will slow until it reaches the terminal velocity. For example, the terminal velocity of a skydiver in a free-fall position with a semi-closed parachute is about 195 km/h (120 mph or 55m/s).[1] This velocity is the asymptotic limiting value of the acceleration process, since the effective forces on the body more and more closely balance each other as the terminal velocity is approached. In this example, a speed of 50% of terminal velocity is reached after only about 3 seconds, while it takes 8 seconds to reach 90%, 15 seconds to reach 99% and so on. Higher speeds can be attained if the skydiver pulls in his limbs (see also freeflying). In this case, the terminal velocity increases to about 320 km/h (200 mph or 89 m/s),[1] which is also the maximum speed of the peregrine falcon diving on its prey.[2] Competition speed skydivers fly in the head down position reaching even higher speeds. The current world record is 614 mph (988 km/h) by Joseph Kittinger, set at high altitude where the lesser density of the atmosphere decreased drag.[1] An object falling on Earth will fall 9.80 meters per second faster every second (9.8 m/s²). The reason an object reaches a terminal velocity is that the drag force resisting motion is directly proportional to the square of its speed. At low speeds, the drag is much less than the gravitational force and so the object accelerates. As it accelerates, the drag increases, until it equals the weight. Drag also depends on the projected area. This is why things with a large projected area, such as parachutes, have a lower terminal velocity than small objects such as cannon balls.
How many seconds does it take a person who stepped off a twelve foot high diving board with zero initial velocity to hit the water?
.866 seconds
What is the average velocity of a person who runs five meters in ten seconds?
.5 meters per second.
How much time does it take a person to walk 12 km north at a velocity of 6.5 km?
1 hour, 50 minutes, 46.15 seconds
Who has the world record in diving?
A person that is good at it.
What is the velocity of someone going north on main street for 1800 m then south on main street for 2200 m and the total time is 400 seconds?
The person travels a total of 4000 m in 400 seconds, so their average speed is 10m/s. However velocity is a vector quantity, and is defined as displacement/time. The total displacement is only 400 m, so the average velocity is just 1m/s.
Why person jumping out of a speeding train fall forward?
The velocity of the person is the velocity of the speeding train plus the velocity of the jump out. this gives a resultant velocity with a forward component in the direction of the train's motion.
On page 115 of your reading material there is a chart showing the distance covered after a specified number of seconds of walking This kind of chart can only be produced in what way?
the person is walking at a constant velocity
Who invented velocity?
the person who discovered velocity was newton. so you should look up newtons theory on velocity.
Is a diving board a lever?
Yes it is. A diving board is a Class 1 lever. The fulcrum is the screws that hold the diving board in place (the rigid part), the load is the person and the effort force is the force the person exerts when he/she braces herself/himself to jump.
Where can one find information on cave diving?
One can find information on cave diving through the cave diving website. Another website to look at is Waves n Caves, and if a person wants to know specifically about cave diving in Britain they can search the cave diving group website.
What is initial velocity?
Initial velocity is the original starting velocity. I love math! It makes you smart like a math smart person.
Zero velocity means vehicle must be stationary?
Zero velocity means that the vehicle and the person who is measuring the velocity are moving together.
