The question includes information that we don't need, and leaves out information
that we do need.
It doesn't matter at all what the mass of the tree is, but in order to answer the question,
we do need to know the mass of the person climbing it.

How long would it take a 7.5 kW motor to raise a 500 kg piano to an apartment window 1000 meters above the ground?
The motor provides energy at the rate of 7500 Joules each second. The energy needed to raise the piano = mass of the piano x acceleration due to gravity x height = 500 x 9.81 x 1000 = 4.905 x 106 Joules time taken = 4.905 x 106 / 7500 = 654 seconds So, it would take around 11 minutes.
How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
How much force is needed to accelerate a 1 kilogram toy car at a rate of 2 meters per second south?
Force is mass times acceleration. Assuming you mean an acceleration of 2 meters per second per second the force is 1 x 2 = 2N, south direction
How many joules of work are needed to life a 15 kilogram mass 3 meters off the ground?
The work done to lift the 15 kg mass is 441 J. This can be calculated by multiplying the weight of the object (15 kg * 9.8 m/s^2) by the height lifted (3 m).
What is the amount of heat needed to raise that temperature of 1 kilogram of water 1 degree Celsius?
The amount of heat needed to raise the temperature of 1 kilogram of water by 1 degree Celsius is 4186 Joules, which is the specific heat capacity of water.
How much energy is needed to move an electron in a hydrogen atom from the ground state n equals 1 to n equals 3 in joules?
1.94 x 10-18 Joules
How much energy is needed to increase the temperature of a kilogram of water 5 degrees?
The specific heat capacity of water is 4.186 J/g°C. Since there are 1000 grams in a kilogram, it would require 20,930 Joules of energy to increase the temperature of a kilogram of water by 5 degrees Celsius.
What is is the amount of heat needed to raise the temperature of one kilogram of water one degree centigrade.?
The specific heat capacity of water is approximately 4.18 Joules per gram per degree Celsius. To raise the temperature of one kilogram (1000 grams) of water by one degree Celsius, it would require approximately 4180 Joules of heat energy.
160j ofwok was needed in order to move an object 8m across a floor What was the force in n that as needed to do this job?
I'm assuming you mean 160 Joules of work.What you need to know for any work questions like this is the formulaWork=Force times DistanceORW=F*DSo in this problem, you're given the Work (160 Joules) and the Distance (8 meters) and you need to find force.Plugging it into the equation:160 Joules= F *(8 Meters)Solving for FF=160 Joules/8 MetersF= 20 Joules/MeterTurns out you're lucky.. 1 Joule/Meter =1 NSo your final answer isF=20N
How much work will be needed to lift a block weighin 4 newtons and a distance of 10 meters?
The work needed to lift the block can be calculated by multiplying the force applied (4 N) by the distance it is lifted (10 m). Therefore, the work required to lift the block would be 40 joules.
Did mount of heat needed to melt 1 kg of a substance?
The amount of heat needed to melt 1 kg of a substance, known as the latent heat of fusion, varies depending on the substance. It is typically measured in joules per kilogram (J/kg).
The amount of heat needed to increase the temperature of one kilogram of substance by 1 and degc?
The amount of heat needed to increase the temperature of one kilogram of a substance by 1 degree Celsius is known as the specific heat capacity of the substance. It is measured in joules per kilogram per degree Celsius (J/kg°C). Different substances have different specific heat capacities due to their molecular structure and composition.
Calculate the work needed to push 50 newton box to a distance of 3 meters?
the answer for this question is 150 nt-m or 150 joules....................why is this my answer, how did i get this?work= newton box X distance (changed into meters)nt-m means joules or the amount of work neededthis is from mrs. macapundag's pupilfor the pshs reviewer 2

How much energy is needed in Joules for a 90 kg woman was to climb a ladder 6 meters in height?
The energy needed to climb a ladder can be calculated using the formula: potential energy = mass x gravity x height. Plugging in the values for the woman's mass (90 kg), height (6 meters), and the acceleration due to gravity (9.81 m/s^2), the energy required would be approximately 5294.2 Joules.
