A single conservative force acts on a 4.70−kg particle within a system due to its interaction with the rest of the system. The equation FX = 2 x+4 describes the force, where FX is in newtons and x is in meters. As the particle moves along the x axis from x = 0.96 m to x = 5.70 m, calculate the following. (a) the work done by this force on the particle (b) the change in the potential energy of the system J (c) the kinetic energy the particle has at x = 5.70 m if its speed is 3.00 m/s at x = 0.96 m J

3.1 A force F→ = (6ı^ − 2ȷ^)N acts on a particle that undergoes a displacement Δr→ = (3ı^ + ȷ^)m. 3.1.1 Find the work done by force on the particle. 3.1.2 The angle between F→ and Δr→. 3.2 The force acting on a particle is Fx = (8x − 16)N, where x is in meters. Find the net work done by this force on a particle as it moves from x = 0 to x = 3.00 3.3 A grasshopper launches itself at an angle of 45∘ from the ground and rises to a maximum height of 1.0 m above the ground. Ignoring the effects of air friction, use conservation of mechanical energy to calculate its initial speed.
