KE=(1/2)mv2
46080 Joules
Kinetic energy is directly proportional to the square of velocity, so the kinetic energy will increase. If the velocity increases from 20 m/s to 32 m/s, the kinetic energy will increase by a factor of (32/20)^2 = 2.56. Therefore, the kinetic energy will be 4500 Joules * 2.56 = 11520 Joules when the velocity is 32 m/s.
Potential Energy equals One Half Mass times Velocity squared. 30kg X 15m/sec X15m/sec =6750 Joules
The kinetic energy of an object can be calculated using the formula KE = 0.5 * mass * velocity^2. Plugging in the values, KE = 0.5 * 175 kg * (3 m/s)^2 = 787.5 joules.
To calculate kinetic energy, first convert pounds to kilograms (1 lb = 0.453592 kg) and miles per hour to meters per second (1 mph ≈ 0.44704 m/s). Then, use the formula KE = 0.5 * mass * velocity^2 to find the kinetic energy. Substituting the mass and velocity values, you can calculate the kinetic energy in 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
The kinetic energy of an object can be calculated using the formula KE = 0.5 * mass * velocity^2. Plugging in the values, KE = 0.5 * 175 kg * (3 m/s)^2 = 787.5 joules.
The energy of a system due to its motion is called kinetic energy. It is directly proportional to the mass of the object and the square of its velocity. Mathematically, kinetic energy (KE) is given by the formula KE = 0.5 * mass * velocity^2.
The object's kinetic energy is 2,500 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 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 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
