- Consider a head-on, elastic collision between twobodies whose masses are m and M, with Itis well known that if m has speed and M is initiallyat rest, m will bounce straight back with its speedunchanged, while M will remain at rest (to anexcellent approximation). Use this fact to predict thefinal velocities if M approaches with speed and mis initially at rest.Prove that in a one-dimensional elastic collision of two equal masses, the particles simply exchange velocities during collisions.How does mass appear to affect the final velocities of both elastic and inelastic collisions?
- Water falls without splashing at a rate of 0.250 L/s from a height of 2.60 m into abucket of mass 0.750 kg on a scale. If the bucket is originally empty, what does thescale read in newtons 3.00 s after water starts to accumulate in it?A block of mass M undergoes a one-dimennational elastic collusion with a block of mass M initially at rest. If both blocks have the same speed after colliding, how are their masses related?two masses A and B are approaching each other with velocities 4.5 m/s and 7.2 m/s respectively. the mass of A is 3.2 kg and B is 5.6 kg. find the velocity after the imapct assumung collision is perfectly inelastic
- A sonar transmitter operates at 2 impulse per second. if the device is held to the surface of fresh water (Eb=2.04E9 Pa) and the echo is received midway between impulses , how deep is the water in meter?In what type of collision was there a decrease in the total kinetic energy? Discuss what happened to the “remaining” energy?What does it mean to say that momentum is conserved in collision? What is elastic and inelastic collisions?
