Question

A BODY TRAVELLS UNIFORMLY A DISTANCE OF (13.8+-0.2)M IN A TIME (4.00+-0.3)S,THE VELOCITY OF THE BODY IS (IN M/S
)

Answer 1

Answer:

V=

time

distance

=

4.0

13.8

=3.45

v

Δv

=

d

Δd

+

t

Δt

=

13.8

0.2

+

4.0

0.3

=0.089

ΔV=0.089×3.45=0.30

∴ Velocity =(3.45±0.3)m/s

percentage error =

V

ΔV

×100=0.089×100=8.9%
