Question
Two cars, both of mass m, collide and stick together. Prior to the collision, one car had been traveling north at speed 2v, while the second was travelling at speed v at an angle theta south of east (as indicated in the figure). After the collision, the two car system travels at a speed vfinal at an angle phi east of north. Express your answers in terms of known quantities.
Find the magnitude of the speed vfinal in terms of v and theta.

Now that you have set up the equation for the x and y components of the final momentum of the firework, let's do some physics! Given: The initial firework had a mass of 9.0 kg and was launched at vi = 110 m/s vertically straight up. The firework explodes into three pieces of equal mass 3.0 kg. The angles θ1 = θ3 = 20 ∘. Speed v1 = 100 m/s. What is the speed v2? Note: the angles shown for mass m1 and mass m3 are relative to the horizontal x axis.

- A ball of mass m moving with velocity v⃗ i strikes a vertical wall as shown in (Figure 1). The angle between the ball's initial velocity vector and the wall is θi as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is Δt , and this collision is completely elastic. Friction is negligible, so the ball does not start spinning. In this idealized collision, the force exerted on the ball by the wall is parallel to the x axis.What is the magnitude F of the average force exerted on the ball by the wall?arrow_forwardA billiard ball moving at 5.95 m/s strikes a stationary ball of the same mass.
