Answer:
If the acceleration is constant, the movements equations are:
a(t) = A.
for the velocity we can integrate over time:
v(t) = A*t + v0
where v0 is a constant of integration (the initial velocity), for the distance traveled between t = 0 units and t = 10 units, we can solve the integral:
Where to obtain the actual distance you can replace the constant acceleration A and the initial velocity v0.
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:
