Question

table tennis ball has a mass 10g and speed of 90ms^(-1) .if speed can be measured within an accuracy of 4% what will be the uncertainty in speed and position.

Answer 1

Keeping in view that, table-tennis ball has a mass 10 g and a speed of 90 m/s. If speed can be measured within an accuracy of 4%.

The uncertainty in position would be; 1.46×10⁻³³m

Answer 2

Table tennis ball with a mass of 10gand a speed of 90m/s .if speed can be measured in within the accuracy of 4% then the an estimate uncertainity speed and position is 90km/h for speed and 1.23×10`10

Am not so sure though but i hope this helps you
