Question

In a ballistic pendulum experiment, suppose the digital timer shows 0.02 s for the time of flight of the projectile. The manufacturer information about the precision of the timer is nowhere to be found. What error would you quote on your measurement

Answer 1

Answer:

The  value is  $\Delta t  =  0.01 \ s$

Explanation:

From the question we are told that

   The time of flight is  $T  =  0.02 \  s$

Given that the value of the time of flight is in three decimal place then the error quote is

     $\Delta t  =  0.01 \ s$
