Impulse & Momentum / Collisions Exercises

Momentum

Given a 45kg object with an initial Velocity of 3.5 m/s. Calculate the objects momentum and how long it would take to stop if a braking force of 12.5 N was to be applied.
Given a 525kg object with an initial Velocity of 12.5 m/s. Calculate the objects momentum and how long it would take to stop if a braking force of 125.5 N was to be applied.

Circle Collisions

Given two circular objects A and B (defined below) which collide with each other, calculate their final velocities:
A: (-2.5, 3.5), radius = 0.15m, mass=0.50kg, and $V_{Ai}=\left[\begin{array}{c}1.1\\2.2\end{array}\right]m/s$
B: (1.4, -2.4), radius=0.20m, mass=0.45kg, and $V_{Bi}=\left[\begin{array}{c}-0.1\\1.2\end{array}\right]m/s$

Sphere Collisions

Given two spherical objects A and B (defined below) which collide with each other, calculate their final velocities:
A: (-2.5, 3.5, 1.1), radius = 0.25m, mass=0.55kg, and $V_{Ai}=\left[\begin{array}{c}0.1\\1.04\\2\end{array}\right]m/s$
B: (1.4, -2.4, -1.1), radius=0.10m, mass=0.35kg, and $V_{Bi}=\left[\begin{array}{c}0.2\\-2.5\\1.1\end{array}\right]m/s$
