is the initial linear velocity of the center of mass immediately after the strike. find its final velocity and displacement.

=−(u−vcosθ)+vu(ucosθ)=−u+vcosθ+vcosθ (This doesn′t cancel directly)equals negative open paren u minus v cosine theta close paren plus v over u end-fraction open paren u cosine theta close paren equals negative u plus v cosine theta plus v cosine theta (This doesn prime t cancel directly) Instead, let's look at the quantity find its final velocity and displacement.

mẌcosα+32mẍ=mgsinαm cap X double dot cosine alpha plus three-halves m x double dot equals m g sine alpha Step 4: Solve for Wedge Acceleration ( Ẍcap X double dot Substitute the expression for ẍx double dot into the second equation: find its final velocity and displacement.

A particle moves along a straight line with a constant acceleration of 2 m/s². If its initial velocity is 5 m/s and it travels for 10 seconds, find its final velocity and displacement.
