How do you work out height from initial velocity final velocity mass and work done?
AlexReynoldsgp8504
If you throw an object up, and assume that air resistance is negligible, knowing the initial velocity is enough. One way to do this is to use conservation of energy. Calculate the energy from the initial velocity, then insert it in the formula for gravitational potential energy.Same for final velocity - the final speed is the same as the initial speed.
If you know the work done, you already have the first half of the above steps solved.

How do you find initial acceleration.?
The initial acceleration of an object can be found by calculating the change in velocity over time. This can be done by dividing the final velocity by the time taken to reach that velocity. The formula for initial acceleration is: initial acceleration = (final velocity - initial velocity) / time.
How do you find work given mass initial velocity and final velocity?
We assume you mean the work done in order to change the velocity of the moving mass.Easiest way is to calculate the change in the kinetic energy of the moving mass, and realizethat it's equal to the amount of work either put into the motion of the mass or taken out of it.Initial kinetic energy = 1/2 m Vi2Final kinetic energy = 1/2 m Vf2Change in kinetic energy = 1/2 m ( Vf2 - Vi2)
What is the amount of work done when a freely falling body falls through a height equal to 1 meter?
Depending on its weight: the amount of work done: A its weight: M free falling body: Vi = 0 A = F.d ( Force x Distance ) = E(initial) - E(Final) = MgH(initial) - MgH(final) H is the height A = MgH with H = 1 m ... A = Mg joules
What is an examples motion?
Initial velocity = m/s, Final velocity =m/s Distance traveled x = mIn this example, the items labeled on the diagram are considered primary: if one of them is changed, the others remain the same. The data in the boxes may be changed, and the calculation will be done when you click outside the box, subject to the constraints described. If the average velocity is directly changed, the final velocity is adjusted for consistency. If the acceleration or time is changed, then the distance is allowed to change.Distance x = m Initial velocity v0 = m/s Final velocity v = m/s Average velocity = m/s Acceleration a = m/s^2 Time t = s

How work is related to powerand energy?
Power is the rate at which work is done. That isPower = Work/Time.Work done is also the change in the total mechanical energy of a system between its initial and final state.Work = Final Energy - Initial Energy
Is your final height based on the height of your parents?
NO IT DEPENDS ON THE GENES, THE TYPE OF FOOD YOU EAT & THE PHYSICAL ACTIVITIES DONE.
Does work depends on time?
Most of them tell that work does not depend on time. Well if we it a person with the same initial and final velocity but different time intervals, the one with lesser time interval will produce greater force and hence more work is done.
7 fundamental and derive quantity for math and physical quantity?
7 fundamental quantities=Area, volume, density , speed/velocity , acceleration , force , work done. Derivation :Area=length x breadth = m x m = 2m (meter square)Volume=length x breadth x height = m x m x m = 3m (meter cube)Density=mass / volume = kg / m³ = kg/m³Velocity=displacement / time = m/sAcceleration=final velocity x initial velocity / time = m/s²Force=mass x acceleration = N (newton)Work Done=force x distance = J (joule)
Initial velocity equals 0 final velocity equals 11.76 mass equals 9 kg. What is the work done?
W=m x vf2 Work equals mass times final velocity squared over 2 2 =11.76 x 92 Square the 9 2 = 11.76 x 81 Then multiply 11.76 by 81 2 = 952.56 Then divide 952.56 by 2 2 = 476.28 Use your sig figs = 4.7 x 102 J Work equals 4.7 x 102 Joules
How do you find the initial velocity?
In kinemetics, i learnt that as long as you have three unknowns, you can solve the problem. If you know the distance, d; time, t; and final velocity, vf; you can figure out vi.average velocity = total distance / total timeso d/t = (vi+vf)/22d/t = vi + vf(2d/t) - vf = vihope this helped .good luckRemember that this only works if the acceleration is constant.-Manvith N
Calculate average force?
Calculating average force can be done in two ways, depending on the given information from the questions First Option: F Average= Final Momentum-Initial Momentum divided by time Second Option: F Average= delta MV (Mass x Velocity) divided by time. hope it helps
