Question

5 or displacement of a body, s= (200 + 5) metrees and time taken
by it t = (20 to.2) gecond, the wind the percentage errone in
the calculation of velocity​

Answer 1

Answer:

3.5%

Explanation:

After evaluating the given values...

∴ s = v × t

Velocity error formula : Δv / v = Δs / s + Δt / t

Δv / v = 5 / 200 + 0.2 / 20 (From the given values)

Δv / v = 0.025 + 0.01 = 0.035

Therefore, percent error = 0.035 × 100 = 3.5%
