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 a hat(i) + b hat(j)

A particle whose speed is 50 m/s moves along the line from A(2,1) to B

1.	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 a hat(i) + b hat(j)
Answer» `2(7 HAT(i) + 24 hat(J))` `7 hat(i) + 24 hat(j)` `11 hat(i) + 26 hat(j)` `8 hat(i) + 24 hat(j)` Answer :A
