Which part of the graph is the object moving the fastest?
C
At A it moved 50m in 25s. 50m/25s= 2m/s
At B it is not moving 0m/35s= 0m/s
At C it moved 30m in 10s. 30m/10s= 3m/s

True or False: If two cars crash and each one pushes on the other with a force of 50 N, then each car feels 100 N of force.
False
Explanation:
When two cars crash and push on each other, they push with the same amount of force in opposite directions. This is called Newton’s Third Law — for every action, there is an equal and opposite reaction.
So if Car A pushes on Car B with 50 N, then Car B also pushes back on Car A with 50 N.
Each car only feels 50 N, not 100 N. You don’t add the forces together on one car because they are acting on different cars.
