Determine the scalar components Ra and Rh of the force R along the nonrectangular axes α and b. Also determine the orthogonal projection P of R onto axis a 030 R - 800 N 110

A uniform rod is rotating on a horizontal plane about a vertical axis through one end with a constant angular velocity ω0. Due to internal shear forces, the rod breaks at the mid-point of its length, and the part with the fixed axis has an angular velocity 1.5ω0 in the same sense. Determine the angular velocity of the other half.

A particle moves along a straight line such that its position is defined by m.

(a) Determine the average velcoity of the particle at t=6 seconds.

(b) Determine the average speed of the particle at t=6 seconds.

(c) Determine the average acceleration of the particle at t=6 seconds.

Identify two true statements about projectiles among the following

1. The horizontal component of velocity always remains constant during projectile

2. The vertical component of velocity remains constant during projectile

3. The vertical component of velocity changes due to the downward gravity

4. The kinetic energy becomes zero at maximum height
