Question

Plz answer the question no 6

Answer 1

K.E=

$\frac{1}{2} m {v}^{2}$

$3 \times {10}^{ - 25} = \frac{1}{2} \times 9.1 \times {10}^{ - 31} \times {v}^{2}$

$v = \sqrt{ \frac{2 \times 3 \times {10}^{ - 25} }{9.1 \times {10}^{ - 31} } }$

$v = \sqrt{ \frac{6 \times {10}^{7} }{91} }$

$v = \frac{2000 \sqrt{1365} }{91}$

Answer 2

Plz use 1/2mv2 formula
