If the distance is known to perfection, an acceleration is constant, then the absolute error in the calculation of acceleration is 2/t3, where t is the measured time.
WE know that ~x*~p>=h/4*3.14 and ~p= m~v so substitute value of ~p in above equqtion
Power is equal to Force times velocity; P=Fv. You are given the 'speed', which I assume to be velocity. You also have acceleration. In order to find F, you need first to find the mass, which you can calculate from the weight, Fg, by dividing by the acceleration due to gravity, 9.8. You then have the mass. From here, multiply mass times acceleration times the velocity.
This is imposible to calculate. In order to find acceleration, knowlege of at least 3 of these variables must be given: initial speed, final speed, distance, and time.
v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration
There is not enough information to calculate pressure. Here are some relevant formulae: Force = mass x acceleration Pressure = force / area
When giving the result of the measurement, its important to state the precision or estimated uncertainty, in the measurement. The percent uncertainty is simply the radio of the uncertainty to the measured value, multiplied by 100. 4.19m take the last decimal unit, is 9 but with value of 1/100 .01 is the uncertainty Now, .01/4.19 x 100 % = 0.24%

certainty means how are you accurate in measuring a physical quantity. There is always some uncertainty in measuring of any physical quantity . It is given by higenberg's uncertainty principle. Quantum mechanics deals with the physical quantities which have some discreet values. So The measurement is not certain.

From here, multiply mass times acceleration times the velocity.
Acceleration is the derivative of the velocity expression. If you have an equation for velocity, simply take the derivative of it and you will have an equation for the average acceleration.
It really depends what information you are given. In the simplest case, you use the definition of acceleration as delta(speed) / time. That is, you divide the change (delta) in speed, and divide by how long it takes for this change in speed. This gives you the average acceleration over the given time. If you assume a constant acceleration, it is also the instantaneous acceleration at any moment.
This is imposible to calculate. In order to find acceleration, knowlege of at least 3 of these variables must be given: initial speed, final speed, distance, and time.

Weight = (mass) x (local acceleration of gravity). Mass = (weight) / (local acceleration of gravity) If you know the weight and the local acceleration of gravity, you can calculate the mass. Anywhere on or near the surface of the earth, the local acceleration of gravity is about 9.82 meters per second2 . As an example, an object with a weight of 9.82 newtons has a mass of one kilogram.
