Question

a car accelerates from 6 metre per second to 18 metre per second in a 12 second calculate the acceleration assuming it to be a uniform​

Answer 1

Explanation:

$u = 6 \: m \: per \: sec\\ v = 12m \: per \: sec \\ t = 12sec \\ a = v - u \div t \\ 12 - 6 \div 12 \\ a = 1 \div 2 \\ a = 0.5m \: per \: s {}^{2}$
