Kinetic energy of a moving object varies directly with the square of velocity If a car moving at 60mph has kinetic energy 180 units how many units of kinetic energy does the same car have at 20mph?
The kinetic energy of the car varies with the square of its velocity. Therefore, if the car is moving at 20 mph (which is one-third of 60 mph), its kinetic energy would be (1/3)^2 = 1/9 of the original kinetic energy. So, at 20 mph, the car would have 180/9 = 20 units of kinetic energy.
How much work is done to increase a 20 kg scooter speed from Ms to 20 ms?
The work done to increase the speed of the scooter can be calculated as the change in kinetic energy. The initial kinetic energy is given by (1/2)mv^2. The final kinetic energy is (1/2)m(20)^2. The work done is the difference between the final and initial kinetic energies.
What is the kinetic energy of a 1 kg mass that is moving with a speed of 20 ms?
The kinetic energy of a moving object is given by the formula 1/2 * mass * speed^2. Plugging in the values for the mass (1 kg) and speed (20 m/s), the kinetic energy would be 200 J.
A small 20-kg canoe is floating downriver at a speed of 2 ms. What is the canoe and kinetic energy?
The kinetic energy of the canoe can be calculated using the formula: KE = 0.5 * mass * velocity^2. Plugging in the values, the kinetic energy of the canoe is 40 J.
If we know the total in a system is 30 joules and we know the poteial energy is 20jolueswhat is the KE?
The total energy in a system is the sum of its potential energy (PE) and kinetic energy (KE). In this case, with a total energy of 30 joules and potential energy of 20 joules, we can use the formula: Total Energy = Potential Energy + Kinetic Energy. So, KE = Total Energy - PE = 30 J - 20 J = 10 joules.

A certain pendulum has a potential energy of 20 J when it is at the top of its swing. What is the kinetic energy?
If at the top of the swing the pendulum is STOPPED then it has zero kinetic energy.
What is the kinetic energy of an object that has a mass of 20 kg and a speed of 2.8m per second?
The object's kinetic energy is 78.4 joules.
If an object weighing 90 kilograms and moving with a velocity of 20 meters per second has a kinetic energy of 4500 Joules. what is its kinetic energy when the velocity is 32 meters per second?
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.
