Question

if u = 5i + 10j m/s a= 2i + 3j m/s^2 t= 5 sec Find:- v=?, s=?​

Answer 1

Explanation:

this is your ans....S IS NOT SURE

Answer 2

For s,

$s = ut + \frac{1}{2} a {t}^{2} \\ s = (5i + 10j)5 + \frac{1}{2} (2i + 2j)( {5}^{2} ) \\ s = 25i + 50j + \frac{25}{2} \times 2(i + j) \\ s = 25i + 50j + 25i+ 25j \\ s = 50i + 75j$

Hope it helps
