2. Initially the 5-kg block is moving with a constant speed of 2
m/s around the circular path centered at 0 on the smooth
horizontal plane. If a constant tangential force F = 5 N is
applied to the block, determine its speed when t = 3 s.
Neglect the size of the block.

F = 5 N
2 m/s
The 10-lb block rests on a surface for which MUK - 0.5, it is acted upon by a radial force of
2 lb and a horizontal force of 7 lb, always directed at 30° from the tangent to the path as
shown. If the block is initially moving in a circular path with a speed V₁ - 2 ft/s at the
instant the forces are applied, determine the time required before the tension in cord AB
becomes 20 lb. Neglect the size of the block for the calculation.

Two identical 16-kg spheres are attached to the light rigid rod, which rotates in the horizontal plane centered at pin Part A: If the spheres are subjected to tangential forces of P = 10 N, and the rod is subjected to a couple moment M=(8t)N⋅mM=(8t)N⋅m, where t is in seconds, determine the speed of the spheres at the instant t = 4 s. The system starts from rest. Neglect the size of the spheres.
