Question

if k=1/2mv2 solve for 'v' and find the value of 'v' if k=100,m=2

Answer 1

SOLUTION :

$\bf K = \frac{1}{2}mv^{2}$

K = 100

m = 2

$\bf K = \frac{1}{2}mv^{2}\\\\=> 100 = \frac{1} {\cancel2 } \times \cancel2 \times v^{2} \\\\=> 100 = v^{2}\\\\=> \sqrt{100} = v\\ \\=> 10 = v$

Hence

v = 10

Answer 2

Answer:

Step-by-step explanation:

K=100, m=2

K=1/2mv2

100=1/2*2*v2

100=v2

V=10 m/s
