A body travels unifromly a distance of (...

A body travels unifromly a distance of `(20.0 +- 0.2)m` in time `(4.0 +- 0.4)s`. The velocity of the body is

A

`(5.0 +- 0.4) ms^(-1)`

B

`(5.0 +- 0.2) ms^(-1)`

C

`(5.0 +- 0.6) ms^(-1)`

D

`(5.0 +- 0.1) ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`V = (S)/(T) implies (Delta V)/(V) = (Delta S)/(S) +(Delta T)/(T)`
