Question

what is s when u=12.65m/sa=18.55,t=7seconds

Answer 1

Hey mate!!!

we know that
s = ut + ½at²

Here u = 12.65
a = 18.55
t = 7
so
s =
$12.65 \times 7 + \frac{1}{2} \times 18.55 \times 49 \\ = 88.55 + \frac{1}{2} \times 908.95 \\ = 88.55 + 454.475 \\ = 543.025$
so $\fbox{543.025 \:is\:your\:answer}$

Hope it helps dear friend ☺️✌️

Answer 2

we know that
s=ut+1/2atsq
putting
12.65×7+18.55×49×1/2
88.55+454.475
543.025
