"Eric is running to school and leaping over puddles as he goes. From the edge of a puddle 1.5 m long, he jumps .2 m high off the ground with a horizontal velocity of 3 m/s. WIll he land in the puddle?"

I said: .2=4.9t^2

.04...=t^2, t=0.2 s

0.2*3=0.6, 0.6 < 1.5 therefore, yes he will hit the puddle.
