Question

A female gymnast weighs 200 N. If she is hanging stationary from a high bar,how many forces are acting on her?

A. one
B.five
C.four
D.two
E.three

WOuld it be choice A or D?

Answer 1

gravity down

tension on arms from bar up
2
net of zero therefore does not accelerate
a body with only one force acting on it must accelerate

Answer 2

To determine how many forces are acting on the female gymnast hanging stationary from a high bar, we need to consider the different forces acting on her.

1. Gravitational force (weight): The female gymnast weighs 200 N, and this weight is acting downward due to gravity.

2. Tension force: The high bar exerts an upward force on the gymnast to support her weight. This force is called the tension force.

So, the answer is D. There are two forces acting on the female gymnast hanging from a high bar - the gravitational force (weight) acting downwards and the tension force acting upwards.

Answer 3

The correct answer is D. There are two forces acting on the female gymnast when she is hanging stationary from a high bar. The first force is her weight, which acts downwards due to gravity. The second force is the tension force exerted by the high bar, which acts upwards to support her. Therefore, there are two forces acting on her: her weight downwards and the tension force exerted by the bar upwards.
