Galactic Alliance Junior Mission Officer (GAJMO) Bundit Nermalloy is predicting the kinetic energy of a supply spacecraft, which is being moved in one dimension in the tractor beam of the ship named the Jadarian-Ruby, to ensure that the supply spacecraft doesn't damage the spaceport to which it is being delivered. GAJMO Nermalloy has been instructed to deliver the supply spacecraft with a kinetic energy less than 10 10 J (where 1 J = 1 N·m). GAJMO Nermalloy knows that the change in kinetic energy of an object moving in one dimension is equal to the net work performed on it, where net work is the integral of the component of net force in the direction of motion with respect to the position of the of the object. That is: KE2 – KE1 = x²² F(x) dx. Րա2 The net force exerted by the tractor beam is supposed to be constant, F = −3.5 × 106 N, but due to improper maintenance of the Jadarian-Ruby, the actual force exerted by the tractor beam as a function of position x is given by F(x) = αx³ + ß,…

Ronaldo is playing outside and shoots a ball of mass 2 kg horizontally with a speed of 8.0 m/s toward a green cart. The mass of the green cart is 15 kg and it rolls at a speed of 1.0 m/s along a horizontal path with no friction. The ball gets stuck in the card. What is the velocity of the cart after the ball strikes it? What are the initial and final kinetic energies of the system? Is the energy conserved in this collision process? What type of collision process is it?
