**Sandhu**, Sunday, October 4, 2009 at 4:23pmSolve for velocity at 2.0s

vx = v0x + axt

vx = (-1m/s) + (0.5m/s2)(2.0s)

vx = 0m/s

vy = v0y + ayt

vx = (3m/s) + (-0.9m/s2)(2.0s)

vx = 1.2m/s

v = 0m/s(x hat) + 1.2m/s(y hat)

Calculate displacement.

∆x = v0xt + 1/2axt2

∆x = (-1m/s)(2.0s) + 1/2(0.5m/s2)(2.0s)2

∆x = -1m

∆y = v0xt + 1/2axt2

∆y = (3m/s)(2.0s) + 1/2(-0.9m/s2)(2.0s)2

∆y = 4.2m

y = -1.0m(x hat) + 4.2m(y hat)
