It describes how quickly or slowly an object moves from one place to another. The standard (SI) unit of speed is meters per second (m/s), but it can also be expressed in other units, such as kilometers per hour (km/h), miles per hour (mph), or feet per second (ft/s), depending on the context or the country's measurement system.
Use this velocity converter to convert instantly between centimeters per second, feet per hour, kilometers per hour, knots, meters per second, miles per hour and other metric and imperial velocity and speed units. Like this?
Apr 18, 2024 · velocity change = 6.95 × 4 = 27.8 m/s. Since the initial velocity was zero, the final velocity is equal to the change in speed. You can convert units to km/h by multiplying the result by 3.6: 27.8 × 3.6 ≈ 100 km/h. You can, of course, make your calculations much easier by using the average velocity calculator.
Convert between speed and velocity units like m/s, km/h, knots, mph and ft/s. Speed is the ratio of covered distance to time and can expressed as. v = s / t (1) where. v = velocity (m/s, km/h, mph ..) s = distance traveled (m, km, miles ..) t = time taken (s, hours ...) The table below can be used to convert between common speed and velocity units:

(a) A player lobs a mid-court pass with a 624-g basketball, which covers 15 m in 2 s. What is the basketball’s horizontal translational kinetic energy while in flight? (b) An average molecule of air, in the basketball in part (a), has a mass of 29 u, and an average speed of 500 m/s, relative to the basketball. There are about 3×10233×1023molecules ...
In part (a), first find the horizontal speed of the basketball and then use the definition of kinetic energy in terms of mass and speed, K=12mv2K=12mv2. Then in part (b), convert unified units to kilograms and then use K=12mv2K=12mv2 to get the average translational kinetic energy of one molecule, relative to the basketball. Then multiply by the nu...
The horizontal speed is (15 m)/(2 s), so the horizontal kinetic energy of the basketball is12(0.624kg)(7.5m/s)2=17.6J.12(0.624kg)(7.5m/s)2=17.6J.The average translational kinetic energy of a molecule is12(29u)(1.66×10−27kg/u)(500m/s)2=6.02×10−21J,12(29u)(1.66×10−27kg/u)(500m/s)2=6.02×10−21J,and the total kinetic energy of all the molecules...v=√2(1.8kJ)/(0.624kg)=76.0m/s.v=2(1.8kJ)/(0.624kg)=76.0m/s.In part (a), this kind of kinetic energy can be called the horizontal kinetic energy of an object (the basketball), relative to its surroundings (the court). If the basketball were spinning, all parts of it would have not just the average speed, but it would also have rotational kinetic energy. Part (b) reminds us that this kind of kinetic energy c...
Oct 11, 2023 · The Kinetic Energy Calculator finds the unknown variable in the physics equation for kinetic energy of a rigid body. Enter the two known variables and the calculator finds the third. KE = 1 2mv2 K E = 1 2 m v 2. Where: KE = kinetic energy. m = mass of a body. v = velocity of a body. The Kinetic Energy Calculator uses the formula KE = (1/2)mv 2 ...
