300 m
90 m
150 m
210 m
Correct answer is C
The acceleration is between the times 3 secs and 8 secs.
Distance = \(velocity \times time\)
= \(30 \times (8 - 3) = 30 \times 5\)
= \(150 m\)
one- to- one
onto
a relation
a series
Correct answer is B
The function \(y = g(x)\) is one- to- one but \(z = h(y)\) is not one- to- one but onto.
\(\therefore h(g(x)) = onto\)
From the diagram above, \(h[g(3)]\) is
S
\(\beta\)
\({s, \beta}\)
\({s, w, \beta}\)
Correct answer is B
From the diagram, \(g(3) = s; h(s) = \beta\).
From the diagram above, which of the following represents the vector V in component form?
\(-5\sqrt{3} i + 5j\)
\(3i + 3\sqrt{3}j\)
\(i + 2\sqrt{3}j\)
\(-2\sqrt{3}i - j\)
Correct answer is B
\(V = V\cos \theta i + V\sin \theta j\)
\(6N = 6 \cos 60 i + 6 \sin 60 j\)
= \(3i + 3\sqrt{3} j\)
3.6 cm
7.6 cm
8.0 cm
11.6 cm
Correct answer is A
Length of arc given angle in radians = \(r \theta\)
= \(4 \times 0.9 = 3.6 cm\)
