    Impossible heisburg uncertainty question that makes no sense

    (a) I plugged all the numbers into the equation using 2pie for h and I get 8.88 and its off by orders of magnitude (b) I have no idea

    What is the Minimum Uncertainty in Block's Speed on a Frictionless Surface?

    The math is right i did a million times. 1.62E-32 is wrong and it was last my chance. thanks, anways...

    Impossible heisburg uncertainty question that makes no sense

    Homework Statement Suppose Fuzzy, a quantum-mechanical duck, lives in a world in which h = 2πJ · s. Fuzzy has a mass of 1.80 kg and is initially known to be within a pond 1.00 m wide. (a) What is the minimum uncertainty in the duck's speed? 1(b) Assuming this uncertainty in speed to prevail...

    What is the Minimum Uncertainty in Block's Speed on a Frictionless Surface?

    1.03E-32 the velocity by 2 and got 5.16E-33 which is wrong by 10% to 100%. I used .003 meters.

    What is the Minimum Uncertainty in Block's Speed on a Frictionless Surface?

    Homework Statement A 1.70 kg block rests on the icy surface of a frozen pond, which you can assume to be frictionless. If the location of the block is measured to a precision of 0.30 cm, what is the minimum uncertainty in the block's speed, assuming the mass is known exactly? Homework...
