Answer 2

Explanation:

Here s=40.0±0.4m and t=5.0±0.6s. Therefore, speed,

v= s/t

= 40.0/5.0

=8.0m s −¹

As y= s/t

, therefore ,

△v = v = △s / s +△t/t

Here △s=0.4m,s=40.0m,△t=0.6s,t=5.0s. Therefore,

or △v / v

= 0.4/40 + 0.6 / 5.0

⇒△v=[0.01+0.12]×8.0=1.04

Hence, v=(8.0±1.04)ms −¹

; percentage error. (△v/v ×100)

=0.13×100=13%
