### Physics Question on Kinetic Energy and Momentum**Problem Statement:**A 1-kg object and a 2-kg object have equal nonzero momenta. Which object has the larger kinetic energy?**Options:**1. The 1-kg object has larger kinetic energy2. The 2-kg object has larger kinetic energy3. Cannot determine from information given4. Both objects have the same kinetic energy**Explanation:**When two objects have equal momenta, their kinetic energies can be compared using the formula for kinetic energy \( KE = \frac{1}{2}mv^2 \) and momentum \( p = mv \). For equal momenta, \( m_1v_1 = m_2v_2 \). To find which object has greater kinetic energy, consider that kinetic energy is proportional to velocity squared; hence even a small velocity has a large impact.

The expression for kinetic energy is given by, K=P22m Here, P is the momentum and m is the mass of the object. It is given that both objects have same momenta. From the equation for kinetic energy, the kinetic energy is inversely proportional to the mass of the object. The object having smaller mass will have larger kinetic energy. Therefore, the 1kg object will have larger kinetic energy.

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 1010 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 = √²² F(x) dx. - x2 x1 The net force exerted by the tractor beam is supposed to be constant, Fo −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) = ax³ +…
