CBSE Class 11-science Answered

An object covers (16.0+- 0.4)m distance in (4.0+- 0.2)s . Find out its speed

Speed = Distance   / time 
 
Distance  d ± Δd = 16 ± 0.4  
 
Time  t ± Δt  = 4 ± 0.2 
 
Speed v = (d/t) ± Δv 
 
Since division is performed to get speed ,
 
relative error in speed ( Δv / v ) = ( Δd / d ) + ( Δt / t ) 
 
( Δv / v ) = ( 0.4 / 16 ) + ( 0.2 / 4 ) = 0.075
 
speed without uncertaintity = d/ t = 16 / 4 = 4 m/s
 
Hence error in speed Δv = 0.075 × 4 = 0.3 m/s
 
Speed with uncertaintity = 4 ± 0.3  m/s
