Answer:
The total tension in the child's neck muscle, T = 56.51 N
Explanation:
Let m = mass of the child's neck
Radius of the curve, r = 2.40 m
The child's speed, v = 3.35 m/s
The tension force on the child's neck when he raises his head up off the floor, 
The tension force on the child's neck when he raises his head from the wall of the slide, 

Since he makes a circular turn in water, the radial acceleration can be given by the equation:


The total tension in the child's neck muscle till be calculated as:

Is related to interfere on raw physical matter (Masses and Bodies)
Answer:
Newtons second law (f=m×a)
Explanation:
The mount of force put into the straw or onto the balloon impacts the acceleratoion and is effected by the mass.
