Question 14Particles A nad B moves on straight lines onhorizontal frictionless plane in the directionsgiven in the figure. A moves on horizontal linewith no acceleration , its initial position is r =5j m. B starts to move from the position, r =А20î m with a constant acceleration of a =В-2î + 2j m/s² with zeroitial velocity. If they20meet each other at point C. Which of thefollowings is the velocity of B when they meeteach other (m/s)?A) (5i+7j)B) (3i+7j)V5C) (4i+6j)D) (-2i+2j)V5E) (2i+5j)V5

Let us consider the coordinates of C is (x, y). Therefore, rA=x,y-0,5=x,y-5rB=x,y-20,0=x-20,y

Particles A nad B moves on straight lines on horizontal frictionless plane in the directions given in the figure. A moves on horizontal line with no acceleration , its initial position is 7, = 5ĵ m . B starts to move from the position, 7 A 20î m with a constant acceleration of d = B -2î + 2j m/s² with zero initial velocity. If they 20 meet each other at point C. Which of the followings is the velocity of B when they meet each other (m/s)? A) (5i+7j) B) (3i+7j)V5 C) (4i+6j) D) (-2i+2j)V5 E) (2i+5j)V5
