Question
Tom the cat is chasing Jerry the mouse across the surface of a table 1.2 m above the floor. Jerry steps out of the way at the last second, and Tom slides off the edge or the table at a speed of 3.5 m/s. Where will Tom strike the floor? 2.72 m from the table what velocity components will he have just before he hits? (Use a coordinate system in which up is positive.) x direction 55 m/s y direction -63.9 your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m/sExplanation / Answer
horizontal velocity is
vx = vo = 5.5 m/s
vertical velocity is
vy = sqrt vo^2 + ( gt)^2
from the kinematic equation
del y = 1/2 gt^2
t = sqrt 2 del y/g
vy = sqrt vo^2 + ( g ( sqrt2 del y/g)^2
= sqrt 5.5^2 + ( 9.8 sqrt 2 ( 1.2)/9.8)^2
=7.33 m/s
