WebNewton’s second law of motion is used to calculate what happens in situations involving forces and motion, and it shows the mathematical relationship between force, mass, and acceleration. Mathematically, the second law is most often written as. F net = m a or Σ F = m a, 4.2. where Fnet (or ∑ F) is the net external force, m is the mass of ... WebQuestion 843094: Pushing a lawn mower requires a force of 200 Newtons. If 4,000 joules of work is performed, how far has the mower moved? Answer by Fombitz(32387) (Show …
Web5. In Figure 3, the net external force on the 24-kg mower is stated to be 51 N. If the force of friction opposing the motion is 24 N, what force F (in newtons) is the person exerting on the mower? Suppose the mower is moving at 1.5 m/s when the force F is removed. How far will the mower go before stopping? WebNewton actually stated his second law in terms of momentum: “The instantaneous rate at which a body’s momentum changes is equal to the net force acting on the body.” (“Instantaneous rate” implies that the derivative is involved.) This can be given by the vector equation. → F net = d → p dt.
