    Would a downhill inclined plane be a simple machine?

    Simply, what the title sugests, would going downhill on inclined plane be considered a simple machine? If so, how is this decreasing the amount of force needed?

    Would a toy car wheel count as a simple machine?

    Homework Statement I currently am confused about a, probably, simple problem >.< Back in primary school and middle school, my science teachers taught me that one of the simplest examples of a wheel and axle would the the wheels of a car (in this case a toy one), which made sense to me at the...

    Simple Projectile Motion Problem

    Alright. So since it appears that the question is not doable without assumptions (i assume? :wink:) Then I will assume that the ball hits the bat when the bat is touching the ground :3.

    Simple Projectile Motion Problem

    Perhaps this is a silly question, but why would the displacement be zero? Were the displacement be zero, would that not mean that the ball is at the start position? (Start position being where the ball is hit). If we were to set the point it hit the ground to be zero, then would we not run into...

    Simple Projectile Motion Problem

    Homework Statement Baseball is hit at 60.0m/s at an angle of 30 degrees to the horizontal. Assuming the field is level find: Time ball was in air How long it was in the air How far did it go Given Assume up is +ve Calculated data within brackets Horizontal v=(52m/s) d= t= Vertical...
