Answer to Question #135544 in Mechanics | Relativity for Afolabi Emmanuel

Question

A car accelerated from 0.54km/h to 0.72km/h in 10 seconds, what is its acceleration

Answer 1

Magnitude of acceleration(a) is defined as-

a = $\frac{v_2-v_1}{t}$

= $\frac{(0.72-0.54)\times60\times60}{10}$

= 64.8 km/h²

= 0.005 m/s²
