Momentum is mass times velocity. So here we can just substitute in our givens and solve for velocity.
.600kg*m/s/.350kg=1.71m/s
Hope this helps! Thank you!
Answer:
This is the equation for elastic potential energy, where U is potential energy, x is the displacement of the end of the spring, and k is the spring constant.
U = (1/2)kx^2
U = (1/2)(5.3)(3.62-2.60)^2
U = 2.75706 J

Explanation:
Vector is perpendicular to x axis or i component.
Hence i component is 0
j component is 63.5

The correct answer is 2.479
