Question

Use the formula
m = ½ sv - 3s²
find the value of v when s = 4, m = 62​

Answer 1

$Given \: s = 4 \: and \: m = 62$

$and \: m = \frac{1}{2} sv - 3s^{2}\: --(1)$

/*Substitute these values in the equation (1) , we get */

$62 = \frac{1}{2} \times 4 \times v - 3 \times 4^{2}$

$\implies 62 = 2v - 48$

$\implies 62 + 48 = 2v$

$\implies 110 = 2v$

$\implies \frac{110}{2} = v$

$\implies v = 55$

Therefore.,

$\red{ Value \: of \: v } \green { = 55}$
