Question

the velocity of an object changes from 50m/s square to 60m/s in 20sec what is the average acceleration of the object a)1m/s square b)2m/s square c)0.5m/s square d)5.5m/s square​

Answer 2

Explanation:

accelaration -

$\frac{fv - sv}{t}$

fv - final velocity

sv- starting velocity

t- time

so ,

$\frac{60 - 50}{20}$

$\frac{10}{20} = 0.5$

so , acceleration is 0.5 m/s option c
