Ksju [112]

Answer

correct answer is C

Head-to-tail method

Here head-to-tail method is employed to determine resultant of vectors.

Let horizontal component be 1 and let vertical component be 2

To add these two vectors. Move vector 2 until its tail touches the head of 1. The tail of resultant of these two vectors touch the tail of vector 1 and head of resultant vector will touch the head of vector 2.

An object is moving at a velocity of 3m/s. It accelerates to a velocity of 5.5m/s over a time of 9 s. What acceleration did it e
alexira [117]

Answer:

Acceleration(a) = \displaystyle\frac{v - u}{t}

v = final velocity = 5.5 m/s

u = initial velocity = 3 m/s

t = time = 9s

\displaystyle a = \frac{3-5.5}{9}

a = \displaystyle\frac{-2.5}{9}

a = -0.278 \ m/s^2 (approx)
