Hello I need helpwith these questions. Consider a 1D collision between two particles. If the collision is neither perfectly elastic nor perfectly inelastic (i.e. ), in addition to the masses and initial velocities, what additional information do you need in order to calculate the velocities after the collision?

A mass ma = 2kg slides down slippery ramp, reaching a speed v = 10 m/s at the bottom. After reaching the level ground ma collides with mass mg = perfectly inelastic collision. 3kg at bottom, sticking together in a a.) What was the height of the ramp, assuming that m, started from rest? b.) How fast were the combined masses ma and mg moving after sticking together? c.) The combined mass runs into a spring, which brings it to a stop after being compressed 7 cm. What is the spring constant k ?

Show calculation and write down what is given and known.  draw a sketch of the system if needed 1. A 10-g bullet moving horizontally strikes and passes through a 4.0-kg block moving with a speed of 4.2 m/s in the opposite direction on a horizontal, frictionless surface. If the block is brought to rest by the collision, and the bullet emerges with a speed of 320m/s, what is the initial speed of the bullet?

Consider the before- and after-collision momentum vectors in the diagram below. Determine the magnitude and direction of the system momentum before and after the collision and identify whether or not momentum is conserved. Finally, determine the magnitude and direction of the net external impulse encountered by the system during the collision. (Hint: Velocity and masses are give) System Momentum Before Collision: _________________________ System Momentum After Collision: _________________________ Is momentum conserved? _________________________ Net External Impulse During Collision: _________________________
