KE=(1/2)mv2
46080 Joules
Potential Energy equals One Half Mass times Velocity squared. 30kg X 15m/sec X15m/sec =6750 Joules
Kinetic energy = 1/2(mass in kg)(meters per second squared ) KE = 1/2(175 kilograms)(3 m/s)^2 = 787.5 Joules
Conversions needed. 175 lbs (1 kg/2.2 lbs) = 79.5 kg ---------------------------------------- 60 mph (1609 meters/1 mi)(1 hr/3600 s) = 26.8 meter per second --------------------------------------------------------------------------------------------now Kinetic energy = 1/2(mass kg)(velocity m/s)2 KE = 1/2(79.5 Kg)(26.8 m/s)2 = 2.9 X 104 Joules --------------------------
Velocity of 4 meters per second??? I will assume so. ( need kilograms, so... 5 grams = 0.005 kilograms ) KE = 1/2mV2 KE = 1/2(0.005 kg)(4 m/s)2 = 0.04 Joules =============
Let's see. Mass constant. 625000 Joules = 1/2(500 kg)V2 1250000 Joules = 500V2 2500 = V2 50 meters/second = velocity ==================================== The velocity doubles if KE doubles.
When the velocity is tripled to 15 meters per second, the kinetic energy will increase by a factor of 9 (3^2) since kinetic energy is proportional to the square of velocity. So, the kinetic energy will be 225 joules (25 * 9) when the velocity is tripled.
The kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph is 2.9 x 105.
Its kinetic energy (in joules) will be (31) times (its velocity in meters per second)2 .
Potential Energy equals One Half Mass times Velocity squared. 30kg X 15m/sec X15m/sec =6750 Joules
Kinetic energy = 1/2(mass in kg)(meters per second squared ) KE = 1/2(175 kilograms)(3 m/s)^2 = 787.5 Joules
That's called kinetic energy. The formula is: Kinetic energy = (1/2) x mass x velocity2. If mass is in kilograms, and velocity (or speed, really) in meters per second, the energy will be in Joules.
The object's kinetic energy is 2,500 joules.
The quantities involved in kinetic energy are mass and velocity. Kinetic energy is calculated as 1/2 the mass of an object multiplied by its velocity squared. The unit of measurement for kinetic energy is joules.
The kinetic energy of a cricket ball depends on its mass and velocity. For example, a cricket ball weighing 160 grams and traveling at a speed of 140 km/h (38.89 m/s) would have a kinetic energy of about 110 joules.
The kinetic energy of the bicycle can be calculated using the formula: KE = 0.5 * mass * velocity^2. Plugging in the values: KE = 0.5 * 10 kg * (3 m/s)^2 = 45 Joules. So, the kinetic energy of the bicycle is 45 Joules.
The kinetic energy of the person can be calculated using the formula: KE = 0.5 * mass * velocity^2. First convert the mass to kilograms (1 gram = 0.001 kg), then plug in the values to find the kinetic energy. The result will be in Joules.
KE = (1/2)mv2 where m = mass (in kilograms), and v = velocity (in meters/second) this gives you the kinetic energy in units of Joules
