  1. R

    X and Y coordinates (in m) to acceleration.

    Thank you, I wasn't sure so I posted the equations I have been using for all of my other problems. I was able to find the correct answer using this help. Thanks a lot!
  2. R

    X and Y coordinates (in m) to acceleration.

    Homework Statement X and Y coordinates of a point are x = 2.2cos(1.2t) and y = 2.2sin(1.2t) (both in m) where t is the time. What is the magnitude of acceleration (in m/s/s). Homework Equations...

    What Elevation Angle Clears the Wall and Hits the Target?

    v = at 20sin(x) = 9.8t 20sin(x) / 9.8 = t s = 1/2(u +v)t 10 = 1/2 * (20sin(x))*(20sin(x))/9.8 Solving for x, the answer for x (the angle) is 44.427 degrees.

    What Elevation Angle Clears the Wall and Hits the Target?

    Homework Statement A projectile, initial speed v = 20 m/s is supposed to hit a target D = 28.9 m away. However an H = 10 m high wall is placed halfway between the launching point and the target. What is the appropriate elevation angle? (in degrees). Homework Equations...
