<span>As the bus accelerates forward, the air inside moves back relative to the bus. The pressure on the back of the bus is higher which will make the balloon floats forward for there is a much lower pressure in front of the bus. Nevertheless, when a short stop happens, the balloon will move backwards due to higher pressure that accumulates in front of the bus. This is an example of general relativity theory where the force you feel when accelerating is indistinguishable from the force of gravity.</span>

siniylev [52]

Answer:

Explanation:

a) The magnitude of the net force on the student = 0 N since the student is standing still on level ground and upward reaction force = downward force.

b) the magnitude of the contact force on the student by the backpack = 80 N since the student was backing the backpack

c) the magnitude of the contact force o the student by the ground = 550 N + 80 N = 630 N reactional force on the student
