Figure P4.26 is the position-versus-time graph for a collision between two carts on a low-friction track. Cart 1 has an in- ertia of 1.0 kg; cart 2 has an inertia of 4.0 kg. (a) What are the initial and final velocities of each cart? (b) What is the change in the velocity of each cart? (c) Do the values culated in part b satisfy Eq. 4.1? (d) Draw a velocity-versus- time graph for this collision. (e) Does cart 1 have a nonzero you cal- acceleration? If so, when, and what is the sign of the accelera- tion? (f) Does cart 2 have a nonzero acceleration? If so, when, and what is the sign of the acceleration? •. Figure P4.26 x (m) 0.6 cart 2 collision cart 2 0.4 0.2 cart 1 cart | t (s) 2 1 -0.2
