Question

A particle whose speed is 50 m/s moves along the line from A (2, 1) to B(9,25). Find its velocity vector in
the form of ai+bj.​

Answer 1

Answer:

Explanation:

Displacement will be final position - initial position

9î - 2î + 25j cap - j cap

=7î + 24j cap

Speed = distance /time

50=25/time (use distance formula which u studied in 10th)

Time = 1/2 seconds

Velocity =displacement /time

V =2î + 24j cap / (1/2)

V=2 (2î +24j cap)
