4.53. Model: Use the particle model for the cat and apply the constant-acceleration kinematic equations. Visualize: Solve: The relative velocity of the cat from the mouse’s reference frame is 0 (4.0cos30 1.5) m/s 1.964 m/s v °− = = Thus, 00 1.964 m/s x vv == and sin30 (4.0 m/s)sin30 2.0 m/s y = ° = . The time for the cat to land on the floor is found as follows: 22 2 11 100 1 0 1 0 1 1 () 0 m 0 m ( 2 . 0 m /
