Question

5. If v=u+at, find: a) u when a=2,t=3 and v= 10 b) t when a=4, u=5 and v=29

Answer 1

Answer:

Step-by-step explanation:

(a) Answer below

$v = u + at$

$(10) = u + (2)(3)$

$10 = u + 6$

$u = 4$

(b) Answer below

$v = u + at$

$(29) = (5) + (4)t$

$29 = 5 + 4t$

$24 = 4t$

$t = 6$

Answer 2

$\text{Hello there!}\\\\\text{Plug in and solve:}\\\\1. \\\\10=u+2(3)\\\\10=u+6\\\\\boxed{4=u}\\\\2.\\\\29=5+4(t)\\\\24=4(t)\\\\\text{Divide by 4}\\\\\boxed{6=t}$
