    Kinectic Energy

    Homework Statement Is it possible for an object to experience a net acceleration, yet maintain a constant kinetic energy? Homework Equations The Attempt at a Solution I think no because the kinetic energy equation is KE = (0.5)mv^2, because KE is not change, so v will not change...

    CIrcular motion

    Homework Statement A object(have mass M1) is placed at a R1 distance from the center of a horizontal surface that can rotate. The surface rotation is very FAST INCREASE ( tangential acceleration is non-negligible) until the surface reaches a cirtical rotation rate. At that instant, the object...

    Projectile Question involving xyz coordinate plane

    Homework Statement Please help me graph this on xyz coordinate plane A golfer strikes the ball of the tee at x=0;y=0;z=0. The hole center is located at a distance of 150m north(+x) and 75m west(+y) of the tee. The upper edge of the hole is 10m below(-z) the height of the tee. If the the...
