Calculate kinetic energy given mass and velocity: Kinetic Energy KE equals 1/2 times mass m times velocity squared v2
Calculate mass given kinetic energy and velocity: Mass m equals 2 times kinetic energy KE divided by velocity squared v2
Calculate velocity given kinetic energy and mass: Velocity v equals the square root of kinetic energy KE divided by one half of the mass m
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.
Kilometers per hour to Meters per second Conversion Example. Task: Convert 75 kilometers per hour to meters per second (show work) Formula: km/h ÷ 3.6 = m/s. Calculations: 75 km/h ÷ 3.6 = 20.8333333333 m/s. Result: 75 km/h is equal to 20.8333333333 m/s.
In Scientific Notation. 25 kilometers per hour. = 2.5 x 10 1 kilometers per hour. ≈ 6.94444 x 10 0 meters per second.
For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s 2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m 2 / s 2. In fact, all energy has the same units, kg m 2 / s 2 ...
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.
