A 56 gram object with initial velocity of 5.0 m/s in the positive x-direction and a 84 gram object moving initially at 2.5 m/s in a direction 210° counterclockwise from the positive x-axis collide in a perfectly inelastic collision. What is their x-component of velocity vx after the collision? Is their y- component of velocity vy after the collision positive or negative?

Question
A 56 gram object with initial velocity of 5.0 m/s in the positive x-direction and a 84 gram object
moving initially at 2.5 m/s in a direction 210° counterclockwise from the positive x-axis collide in a
perfectly inelastic collision. What is their x-component of velocity vy after the collision? Is their y-
component of velocity vy after the collision positive or negative?
O vy = +0.70 m/s , vy = positive
%3D
Ov = +0.70 m/s, vy = negative
O Vx = -0.70 m/s , vy = negative
O v = +0.42 m/s , v, = positive
O vx = +0.42 m/s , vy = negative
