I got 8.91 m/s. Correct?

Homework Statement A particle leaves the origin with a velocity of 7.2 m/s in the positive y direction and moves in the xy plane with a constant acceleration of (3.0i - 2.0j) m/s2. At the instant the particle moves back across the x-axis (y=0), what is the value of its x coordinate...

For the value of ax is it 2 m/s2?

Ok thanks

Sorry I don't know how to do superscript and subscript. I should be able to find time from the first equation for solving for t right?

Is it v^2xf = v^2xi + 2ax(xf-xi) ?

Ok, can I use the Vxf (velocity in the x direction, final) = Vxi + ax*t to find t?

Homework Statement At t=0, a particle leaves the origin with a velocity of 9.0 m/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 partice is 15 m, what is the speed of the particle? Homework...
