Hello I need some help with these questions. If you could please show me all your work on a separate sheet of paper with the solutions/answers that would be great!

1. Two cars collide at a 90-degree angle in a completely inelastic collision. One car was 1.25 x 10* kg travelling at 62 km/h [S]; the other car of mass 2.5x10* kg was travelling at 55 km/h [W]. If the cars have a completely inelastic collision, what is their velocity just after the collision? 2. In a game of marbles, a collision occurs between two marbles of equal mass m. One marble is initially at rest; after the collision, the marble acquires a velocity of 1.10 m/s at an angle of 0 = 40.0 from the original direction of motion of the other marble, which has a speed of 1.36 m/s after the collision. What is the initial speed of the moving marble? (a) ty +X (at rest) VIX = ? m m (b) ty 1V2'/= 1.10 m/s V 2' -+X V2'y = (1.10 m/s) sin 40.0 2 0 = 40.0 V2'x = (1.10 m/s) cos 40.0 Vi'x = (1.36 m/s) cos 1 Viv = - (1.36 m/s) sin $ Figure 3 (a) Initial situation Ivi'l = 1.36 m/s (b) Final situation
