Question
![3a).Two equal-mass hockey pucks undergo a glancing collision. Puck 1 is initially at rest and is
struck by puck 2 travelling at a velocity of 13 m/s [E]. Puck 1 travels at an angle of [E18°N]
after the collision. Puck 2 travels at an angle of [E4°S].
a) Draw the diagram and determine the final velocity of each puck.
b) What is the total kinetic energy
i)
before two hock pucks collision?
ii)
after the collision?
iii)
Compare your answers in the i) and ii). Explain your results.
3e). Use the concept of momentum and initial frame of reference to explain how child car
seats help protect children riding in motor vehicles. Describe some ways that the design of
standard child car seats or the materials used in them might be improved.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F70eedff9-4a89-4f92-bf76-bf9f17bfd23a%2Fffe7a973-24d2-4ff9-bef1-9293152e139c%2F29liuir_processed.jpeg&w=3840&q=75)
