What has greater kinetic energy a 1 lb ball rolling down a hill a 200 lb person running down a hill or a car driving down a hill?
The car driving down a hill will have the greatest kinetic energy due to its larger mass and likely higher velocity compared to the 1 lb ball rolling and the 200 lb person running down the hill. Kinetic energy is calculated as 0.5 * mass * velocity^2, so a higher mass and velocity will result in greater kinetic energy.
How many lb equal 352 lb?
352 lb equals 352 lb.
A pull of 2500 lb is required to move a boudler 6 in what is the heat equivatent of the work performed?
The work done to move the boulder is equal to the force applied multiplied by the distance moved, which gives 2500 lb * 6 in = 15000 lb-in. To convert this to heat energy, we need to consider the heat equivalent. If we assume 1 lb-in is equal to 0.00029256 kWh, then the heat equivalent of the work performed would be 15000 lb-in * 0.00029256 kWh = 4.39 kWh.
A force of 50.0 lb is used to push a box 10.0ft across a level floor. A) how much work was done on the box B) what is the change of potential energy as a result of this move?
A) The work done is calculated by multiplying the force by the distance moved. So, 50.0 lb * 10.0 ft = 500.0 ft-lb of work done on the box. B) Since the floor is level, the potential energy remains constant as there is no change in elevation.
How many btus are required to change 10 pounds of steam at 212 degrees to 240 degrees?
To calculate the heat energy required to change the temperature of a substance, you can use the formula: Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Given that steam has a specific heat capacity of approximately 0.5 btu/lb°F, you can calculate the required heat energy by plugging in the values: Q = 10 lb * 0.5 btu/lb°F * (240°F - 212°F).
What is wood's energy?
According to the information I found, in the laboratory, you can get 8660 BTU/lb out of wood because you can make it completely dry. However, moisture in the wood affects its energy output because energy is wasted to heat and expel the water content. They say that the realistic energy output of wood is closer to 6050 BTU/lb. 6050 BTU/lb = 6383 kilojoules/lb
What has more fuel energy petrol or diesel?

Calculate the kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph?
The kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph is 2.9 x 105.
What has greater kinetic energy a 1 lb ball rolling down a hill a 200 lb person running down a hill or a car driving down a hill?
The car driving down a hill will have the greatest kinetic energy due to its larger mass and likely higher velocity compared to the 1 lb ball rolling and the 200 lb person running down the hill. Kinetic energy is calculated as 0.5 * mass * velocity^2, so a higher mass and velocity will result in greater kinetic energy.
If 1 lb of fat is stored by the body for each 0146 J of excess nutritional energy consumed how many bags of chips contain enough nutritional energy to result in 1 lb of body fat?

is it possible for someone 50 lb overweight to be in energy balanc
What is the kinetic energy of a 22500 lb truck traveling 55 mph?
The kinetic energy of the truck can be calculated using the formula KE = 0.5 * m * v^2, where m is the mass of the truck and v is its velocity. First, convert 22500 lb to kg (1 lb ≈ 0.4536 kg) and 55 mph to m/s (1 mph ≈ 0.44704 m/s). Then plug the values into the formula to calculate the kinetic energy in joules.
How many watts of electrical energy are equal to 1 lb?
Watts represent the rate of using energy. (Joules per second). 1 lb is a weight. It's like asking how many sheep per second are equal to a house.
Is the Whirlpool LTE5243D energy star compliant?
Whirlpool's LTE5243D is an Energy Star compliant 18 lb dry load washer/dryer.
How many lb equal 352 lb?
352 lb equals 352 lb.
6 tons 300 pounds minus 2 tons 900 pounds equals what?
Probably simplest (easiest not to get mixed up) to convert both to lb, subtract, then convert back to tons. 1 ton = 2000 lb, so: 6t 300 lb = 6x2000 lb + 300 lb = 12000 lb + 300 lb = 12300 lb 2t 900 lb = 2x2000 lb + 900 lb = 4000 lb + 900 lb = 4900 lb 12300 lb - 4900 lb = 7400 lb convert back to tons: 7400 lb/ 2000 lb per ton = 3 tons 1400 lb
