Question

A body travels uniformly a distance of (13.8 ±0.2) m in a time (4.0 ± 0.3) s. calculate the velocity of the body within error limits.what is the percentage error in speed

Answer 1

Answer 2

The speed error percentage is 3.19%.

We divide the distance by the time to determine the body's velocity:

Distance x time equals velocity.

With the values and error limits provided, we have:

Distance: (13.8 m + 0.2 m)

Time = (4.0 ± 0.3) s

Distance divided by time results in:

Velocity is equal to 13.8 m/s / 4.0 m/s.

Velocity is 3.45 m/s x 0.11

As a result, the body's velocity is 3.45 0.11 m/s, within acceptable error bounds.

We can use the following formula to determine the speed mistake percentage:

Error Value = (Error / Value) x 100%, where

When we change the values, we obtain:

Error in Percentage = (0.11 / 3.45 x 100%)

Error percentage: 3.19%

Hence, the speed error percentage is 3.19%.
