In reviewing her lab book, a physics student finds the following description of a collision: " a 4 kg air hockey puck with an initial speed of 6 m/s to the right collided head on with a 1 kg puck moving to the left at the same speed. After the collision, both pucks traveled to the right, the 4 kg puck at 2 m/s and the 1 kg puck at 10 m/a." Is momentum conserved in this description? Is kinetic energy conserved on this description ? Could this collision actually have taken place as described? Source: physics: a conceptual world view
In an Atwoods Machine lab with m1 = 0.1 and m2 = 0.13 observed acceleration is 1.20 m/s^2. Compare the value with the a(theoretical). During the momentum collision lab a 2.5kg mass moving with 2m/s hits a stationary 5kg mass. After the collision 2.5kg bounces back with 0.5m/s and 5kg mass moves with 1.2 m/s. Calculate Pi and Pf and compare using percent error. Does this experiment show conservation of momentum?
A 12 kg block, initially moving to the right, collides with a stationary 18 kg block, causing the 18 kg to move off to the right. The collision is perfectly elastic. We may conclude that after the collision, the 12 kg block will stop. move to the right with less speed than it had before the collision. move to the right with the same speed that it had before the collision. move to the left with less speed than it had before the collision. move to the left with the same speed that it had before the collision.
