Question

A car increases it’s speed from 20 km/h to 50 km/h in 10 seconds.Find the acceleration

Answer 1

$\huge\tt{Answer:-}$

Acceleration:- v/t

$\huge\tt{a=(v2-v1)\div(t2-t1)}$

$\huge\tt{30 \times 3 \div 18m/s}$

$\huge \tt {25\div3m/s}$

$\huge \tt {t2 - t1 = 105}$

$\huge \tt {a=25÷(3×10)}$

$\huge \tt\pink{5÷6^2m/s ←Ans}$

Hopes it helpful for u :)
