- (a) State the principle of conservation of momentum. (b) A trolley X of mass 2 kg moving at 10 m s-¹ hits a stationary trolley Y of mass 3 kg. After a collision, the two trolleys stick together. i. 2 kg 10 m s¹¹ ii. X Before collision Y 3 kg Calculate the momentum of trolley X before the collision. Find the common velocity of trolley X and Y after the collision. iii. If the time of impact is 0.5 s, find the average force acting on trolley X. After collision iv. Is the collision elastic or inelastic? Show your calculation to explain your answer.An air hockey puck is sliding over an air-hockey table with an initial velocity of -20 m/s until it's hit by...that thing you hit the puck with in air hockey...and its velocity afterwards is 4 m/s. If the mass of the puck is 0.1 kg, then what is the impulse delivered to the air hockey puck? Write your answer in units of N*s, but only write down the number part of your answer. O 1.2 O4 2.4 O22. A 400.0 g cart moving at 0.360 m/s has how much momentum? (careful...units!) 3. If the cart in question 2 was to bounce back and return with a velocity of -0.240 m/s , what is its change in momentum (remember that momentum is a vector quantity)? This change in momentum is called the impulse.
