Question

two forces each of size 8N have a resultant of 13N.
a) Find the angle between the forces.
b) the two given forces of magnitude 8N act on a particle of mass m kg, which remains at rest on a horizontal surface with no friction. the normal contact force between the surface and the particle has magnitude 7N. find m and the acute angle that one of the 8N forces makes with the surface. ​

Answer 1

Answer:

angle= cos inverse (41/128)°

Explanation:

resultant= √a2+b2+2ab cos theta
