Question

ii) The distance travelled by an object in time
(100 + 1) s is (5.2 + 0.1) m. What is the
speed and it's error?​

Answer 1

please mark it as a brainlist ..

We have t=100 s

And delta t=1 s

And d=5.2m

, delta d=0.1m

Now speed = distance /time

By the method of ➗ dividation error

Then

S/deltaS= delta d/d + delta t /t

=0.1/5.2+1/100

=1/52+1/100

Then percentage error of speed

delta s/s%= 1/52×100+1/100×100

=100/52+1

= 1.923+1

2.923% . That's the percentage error in speed.
