Question

The formula v=at +16t² is used in mechanics.Rewrite to nake a the subject and find it's value when v=27 and t=4​

Answer 1

Answer:

$v = at + 16 {t}^{2} \\ v - 16 {t}^{2} = at \\ \frac{v - 16 {t}^{2} }{t} = a \\ (27 - 16 \times {4}^{2}) \div 4 = a\\ \frac{27 - 256}{4} = a\\ \frac{ - 229}{4} = - 57.25 \\ thank \: you$
