Homework Help: Physics

Posted by Lady22 on Thursday, February 24, 2011 at 7:22pm.

A projectile is launched with an initial speed of 40m/s at an angle of 25 degrees above the horizontal. The projectile lands 3 sec. later. Neglect air friction.

What is the projectile's velocity at the highest point of it's trajectory?

What is the straight line distace from where the projectile was launched to where it hits its target? note that the hill may slope up or down from the launch point.

I'm lost, any help would be great;)
