Child rides the Gravitron at the carnival. What force acts as the centripetal force on this ride?

Assume the child has a mass of 50 kg. Calculate her weight.

Due to her inertia and weight, the child's tendency would be to slide down the wall. What force acts upward to keep her from sliding down the wall?

Assume that she has a tangential speed of 10 m/s and the ride has a radius of 3 meters. What is the magnitude of the normal force acting on her?

E. Assuming she does not slide, the vertical (upward and downward) forces in the diagram must be equal. What minimum coefficient of friction is required between the wall and the child to keep her from sliding?

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero. 

The best answer i can think of is b
