The horizontal surface on which the block of mass 2 kg slides is frictionless. The force of
24 N acts on the block in a horizontal direction
and the force of 72 N acts on the block at an
angle as shown below.
72 N
160°

What is the magnitude of the resulting ac-
celeration of the block? The acceleration of
gravity is 9.8 m/s.

The solid that is formed and usually sinks to the bottom of a solution is the

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
