Question 1

how can we prove the impulse equation using a trolley and mass (CP9)

Answer 1

using a pully, weights, motion sensor, datalogger, and trolly we can record how different forces overtime periods can cause the trolly to accelerate to different velocities, then find the impulse then plot a graph with an impulse on the y axis, and change in velocity on the x-axis then a straight line (best fit) through the origin should occur proving the impulse equation ( mass

Question 2

the gradeint of a P x v graph is

Answer 2

mass of the accelerating object

Question 3

what is impulse

Answer 3

a force acting for a certain time causing a change in momentum I=ft

Question 4

using frame by frame analysis what can we do to verify the conservation of momentum in 2D

Answer 4

we can isolate both dimensions of the object and then find the p in each dimension
