Question

The distance travelled by a vehicle in time (25+-2)sec(8.2+-0.3)m.what is the speed and it's error.​

Answer 1

Answer:

What is the the meaning of of error

Answer 2

Answer:

here,

t = 25+-2sec

s = 8.2+-0.3 m

therefore speed,

v = s/t

v = 8.2/25

= 0.328

as y = s/t therefore, deltaV/V = delta s/s+delta t/t

here, delta s= 0.3, s= 8.2, delta t = 2, t=25

therefore, delta v/ v = 0.3/8.2 + 2/25

= 0.04 + 0.08

= 0.12m
