Correct answer is C
a = \(\frac{F}{m} = \frac{100}{0.15} = 666.7\)
v = u + at
= 0 + 66.7 x 0.03
= 20m/s2

Correct answer is A
K = \(\frac{F}{e} = \frac{4}{0.16} = 250\)
F = \(\frac{1}{T} = \frac{1}{2 \pi \frac{\sqrt{m}}{k}}\)
= \(\frac{1}{2 pi \frac{\sqrt{0.5}}{250}}\)
= 10\(\sqrt{5}\)

Correct answer is B
v = \(\sqrt{U^2} + 2as = \sqrt{0^2} + 2 \times 2 \times 9 = 6\)m/s
s = (\(\frac{v - u}{2}\))t
s = (\(\frac{v + 2u}{2}\))t
s = (\(\frac{v + u}{2}\))t
s = (\(\frac{2v + u}{2}\))t
Correct answer is C
