Question

if t = v-u/a find the value of a if t=3, v=2 1/2 and u= 1 1/3​

Answer 1

Answer:

The value of a is 7 /18

Step-by-step explanation:

t= ( v- u ) / a

t= 3, v=2, 1/2=(2× 2 +1) / 2= 5 /2

u = 1 1/3= ( 3 ×1 + 1) /3 =4/3

Putting the value in the equation,

3 = {(5 /2 ) - ( 4 / 3)} / a

3 a = ( 5 ×3)/(2 × 3)} - { (4 × 2) / (3 ×2)}

3a = (15 /6 )- (8 / 6)

3a = (15 - 8 )/ 6

3a × 6 = 7

  18 a= 7

  a = 7 / 18

Answer 2

Answer:

Hence,the value of a is $a=\frac{7}{18}$

Step-by-step explanation:

Given-

t=3

v=$2\frac{1}{2}$ and u= $1\frac{1}{3}$

We have to find the  value of a

Solution-

t=3

v=$2\frac{1}{2} = \frac{4+1}{2} =\frac{5}{2}$

u=$1\frac{1}{3} =\frac{3+1}{3} = \frac{4}{3}$

As we know that,

$t=\frac{v-u}{a}$

Put the given values in these formula we get

$3=\frac{\frac{5}{2}-\frac{4}{3} }{a}$

$3a=\frac{5}{2} -\frac{4}{3}$

$3a=\frac{15-8}{6}$

$a=\frac{7}{6\times\\3}$

$a=\frac{7}{18}$

Hence,the value of a is  $a=\frac{7}{18}$
