Web4 Answers. Sorted by: 1. The equation of equilibrium in the vertical direction is F sin θ + F f − m g = 0, where F f is the friction force (if its sign is positive, it is directed upwards), so F f = m g − F sin θ. However, if m g − F sin θ > μ s F cos θ, the problem does not have a solution (the block cannot be in equilibrium). WebSep 12, 2024 · Thus, the magnitude of centripetal force F c is. Fc = mac. By substituting the expressions for centripetal acceleration a c ( ac = v2 r; ac = rω2 ), we get two …

WebFeb 2, 2024 · To find the normal force of a book lying on a horizontal surface, you need to multiply the book's mass (0.6 kg) and gravitational acceleration (9.807 m/s² ). Are normal force and weight always equal? Normal force and weight aren't always equal. They're equal when: There are no other forces exerted in the vertical direction; and
WebNow think of Newton's 3rd law of motion: Every action has an equal and opposite reaction. The force will be divided between the two blocks and they will both move away from each other at 2.5 m/s assuming no energy lost in the collision.
