Homework Statement
At t=0, a particle leaves the origin with the velocity of 9.0m/s in the positive y direction and moves in the xy plane with a constant acceleration of ( 2.0i-4.0j) m/s ^2 . At the instant the x coordinate of the particle is 15 m , what is the speed of the particle ?
Homework Equations
V=u+aT , X= ut+ .5at
The Attempt at a Solution
X coordinate: X=ut+.5at
15= 0+ 2t
find t and plug it in the y - coorodinate
y coordinate : V=9-4t
Is that corrected ?
