A 36-g ball at the end of a string is swung in a vertical circle with a radius of 19 cm. The tangential velocity is 200.0 cm/s.
STALIN [3.7K]

Answer:

0.758 N

Explanation:

mass of ball, = 36 g = 0.036 kg

radius, r = 19 cm = 0.19 m

tangential velocity, v = 200 cm / s = 2 m /s

The tension is the string is equal to the centripetal force acting on the ball.

The centripetal force acting on the ball is given by

T=\frac{mv^{2}}{r}

T=\frac{0.036 \times 2 \times 2}{0.19}

T = 0.758 N

Thus, the tension in the string is given by 0.758 N.

All of the following show friction as a useful force, except
Troyanec [42]

having to push a rough and heavy box across the floor to move it

Explanation:

Friction is not a useful force because we have to exert even more force to push a body that is rough and heavy across the floor to move it.

  • Frictional force is a force that opposes the motion of a body.
  • It costs more and uses more energy to push a rough and heavy box on surface because of friction.
  • This wastes energy in systems that deals with pushing.

Friction is useful in that:

  • the heat energy produced when two surfaces rub together  is very useful.
  • the friction between your feet and the floor keeping you from slipping  and makes walking possible.
  • the tread on tires helping the moving vehicle slow down and stop when necessary.
