Finding it hard to visualise, are u able to draw it out and derieve it?Two particles A and B start at the origin O and travel in opposite dirctions along the circular path at constant speeds V₁ = 0.7 m/s and VB = 1.5 m/s, respectively. Determine in ₺ = 2 s, a) the displacement along the path of each particle b) the position vector to each particle c) the shortest distance between the particles B 5 m UB=1.5 m/s VA = 0.7 m/s xA van had a small light in the ceiling of the cargo bay. When the van is accelerating east at a rate of 2.99 m/s^2, the light bulb rattles loose and falls to the floor. Determine the acceleration relative to the earth and its direction and the acceleration relative to the van and it’s direction.
