Question

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

HERE IS YOUR ANSWER MATE :-

Time with error = 100 ± 1

here , ∆ t = 1 & t = 100

Distance with error = 5.2 ± 0.1

here , ∆s = 0.1 & s = 5.2

Now, ∆v = ∆t + ∆s

∆v = 1+ 0.1

∆v = 1.1

also, speed = distance / time

v = 5.2/100

v = 0.052

hence , speed with error =

(0.052 ± 1.1)
