Question

The equation below is the solution to a problem.

[(2.00kg)(8.0m/s)^2]/5.00m = 6.00N - (2.00 kg)(9.8 /s^2) (cos 180°)

The best physical representation of this equation is

a sphere of 2.00 kg mass under a 6.00 N tension when at the bottom of a vertical circle.

a sphere of 2.00 kg mass under a 6.00 N tension when at the side of a vertical circle.

a sphere of 2.00 kg mass under a 6.00 N tension when at the top of a vertical circle.

a sphere of 2.00 kg mass at any point on a horizontal circle.

a 2.00 kg gecko running on the ceiling with a speed of 8.00 m/s.

Answer 1

[(2.00kg)(8.0m/s)^2]/5.00m = 6.00N - (2.00 kg)(9.8 /s^2) (cos 180°)

[(2.00kg)(8.0m/s)^2]/5.00m = 6.00N + (2.00 kg)(9.8 /s^2)

mv^2 / r = T + mg

The best physical representation of this equation is

a sphere of 2.00 kg mass under a 6.00 N tension when at the top of a vertical circle. (ANS)
