    Momentum of projectile, i think

    Please post in the proper format, because it makes it easier to answer questions. Also, a diagram would really help me understand this question if you can post one.

    Friction and Acceleration in Inclined Surfaces

    While your formula, f=ma, is mostly correct, you have not applied it properly. The fact that the force is applied at an angle changes the situation, and you need to reconsider how you calculate the force. Also, why I said mostly correct is because you failed to include the sum F=ma. You...

    Vectors. Calculating Weight (N) of Plane with force and angle of take off

    Hey, I'm kind of new to physics, but it seems to me that the fact that the vertical component of velocity is constant tells you something about the acceleration in the vertical direction. I think that should help.

    What is the angle of a suspended rod supported by two springs?

    Okay, so I divided the force due to gravity by 2 and worked through the problem and got the answer. I hadn't considered that the springs would share the restoring force. Thanks for the help!

    What is the angle of a suspended rod supported by two springs?

    Homework Statement A uniform 1.3-kg rod that is 0.71 m long is suspended at rest from the ceiling by two springs, one at each end of the rod. Both springs hang straight down from the ceiling. The springs have identical lengths when they are unstretched. Their spring constants are 57 N/m and...
