3.2 The not force acting on object A is zero between 10s and 1 = 20$ Use the graph and a relevant equation to explain
why this statement is TRUE
3.3 Calculate the magnitude of the impulse that object A experiences betwee
= 20 s and f = 50 S
(3)
At = 50 s. object A collides with another object. B. which has a momentum o
70 kg-
msEAST
Use the information from the graph and the relevant principle to
3.4 Calculate the momentum of object B after the collision
