Homework Statement
A cat crouches on the floor at a distance of 1.7 m from a desk chair of height 0.45 m. The cat jumps onto the chair , landing with zero vertical velocity. The desk chair has coasters and rolls soomthly away when the cat lands. The cats mass is 6.4 kg , the chairs mass is 12 kg. what is the speed of recoil of the chair and cat?
The Attempt at a Solution
1/2gt^2=0.45m
t=0.303s
1.7/0.303=5.61ms horizontal velocity component
5.61*6.4=12v
v=2.99m/s
