If a stone falls past a bird on a ledge moving at 4ms how fast will the stone be moving just before it hits the ground below 9 seconds later?
A 92.2 m/s V = (4 m/s) + (9.8 m/s²) (9 s) V = 92.2 m/s
11 cm is how many meters?
.11 meters You are just moving the decimal place two spaces to the left. 100cm=1m
A model airplane flys 18 feet in 2 seconds what is the airplane speed in miles per hour?
If an object is moving 18 feet in 2 seconds, then it is moving 64,800 (18 times 60 times 60) feet in one hour. That is 12.3(64,800 divided by 5,280) miles per hour.
How fast are you moving if you're traveling 50 feet in the span of 3 seconds?
Speeds are given in terms of distance per time (for example, miles per hour is a common unit for speed). This means that you simply divide 50 feet by 3 seconds to get 16.67 feet per second. That is a perfectly valid unit for speed, but you could express the same speed as 5.08 meters per second or 11.36 miles per hour.
How do you convert radians per second to meters per minute?
First you must know the radius of whatever is moving in a circle. The relationship is: linear speed (meters/second) = angular speed (radians/second) x radius. The result, as hinted in the units, will be in meters/second. Converting that to meters/minute is easy; you just multiply by 60.
Jack can run at 75 meters in 10 seconds how fast is he moving?
Jack is moving at a speed of 7.5 meters per second.
Who was travelling faster than the other a person who covered 10 meters in 5 seconds or the one who took 10 seconds to cover 20 meters?
Someone traveling 10 meters in 5 seconds is moving at the same speed as the one going 20 meters in 10 seconds.
What is the velocity of a ball that has a 3.03 second hit to the ground?
If it was thrown horizontally or dropped, and hit the ground 3.03 seconds later, then it hit the ground moving at a speed of 29.694 meters (97.42-ft) per second. If it was tossed at any angle not horizontal, and hit the ground 3.03 seconds later, we need to know the direction it was launched, in order to calculate the speed with which it hit the ground.
The cheetahs speed averages 70 meters per sec how far does it travel in 5 sec?
If it's moving at 70 meters per second, and it's moving for 5 seconds..Simple math. 70 x 5 = 350 meters in 5 seconds.
How fast would the man be moving if he travels from 10 meters to 0 meters in 5 seconds?
10 metres in 5 seconds or 2 metres per second.
How fast is an object moving if it travels 350 meters in 7 seconds?
The object is moving at the speed of 50 ms-1 .
A car accelerates from rest at 2 meters per second per second What is its speed 3 seconds after the car starts moving?
6 meters per second. Explanation: After 1 second = 2 meters per second. After 2 seconds = 4 meters per second. After 3 seconds = 6 meters per second.

What is the kinetic energy of a car that has a mass of 2400 kg and is moving at twenty meters per seconds?
480 000 J
How do you calculate the velocity of a moving object?
The change in distance divided by change in time. So say it moved 10 meters in 5 seconds, it would be 2 meters per second.
