Question
![1.) A 100-lb block slides down a frictionless
inclined plane at an angle of 60° with the
horizontal. Determine the accelerating
force, the required to travel the first 20ft and
the time required travel the next 20ft.
2.) A 100-lb is attached to a rope and is
pulled upward with a force of 1501lb. What is
the upward acceleration of the body?
3.) A 12-kg block is acted upon by two
forces that in opposite direction, one a
540N and the other of 1260N. Determine the
acceleration produced. How is the direction
of the acceleration related to the forces?
4.) 3.5-kg block rest on a horizontal
tabletop. A cord is attached to this block,
the cord passing over pulley at the edge
of the table. At the end of the cord is hung
another block weighing 5N. Determine the
tension in the cord and the distance the
blocks move after 2 seconds.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F43a918dd-62c5-4c3c-8dbc-f765cc591511%2Fbc915784-864f-44f4-9b6b-a6734f7cb7df%2Frhhlyl_processed.jpeg&w=3840&q=75)
