Ответ:
The net force on the balloon is zero, so it has no acceleration. So by Newton's first law, if the balloon has some velocity in a given direction, it will continue moving in that direction at a constant speed. If it's motionless, it stays motionless.
Ответ:
B
Explanation:
F= m×a
450N = 1.5kg × a
450/1.5 = a
a=300m/s²
