Answer:
12) s=
13) A=wh
14) p=a+b+c
15) A=
16) p-b-c=a
Step-by-step explanation:
12)
13) =W (multiply both sides by h)
14) take c to the other side of the equation( other side of the equal sign) it becomes a positive value
15) Divide both sides by 2
16) take b + c to the other side of the equation where it becomes -b-c
Answer:
-3.92 N
Step-by-step explanation:
We are given that
Mass of ball=0.4 kg
Acceleration due to gravity=
Because the ball flies against to gravity
We have to find the net force acting on the ball while it is in motion.
We know that when there is no air resistance then the net force acts on the ball is equal to weight of ball.
Net force,F =mg
Substitute the values then we get
Hence, the net force acting on the ball while it is on motion=-3.92 N
