What is Fg, the force on the ball due to the Earth, at t=0? Your answer must be a vector with appropriate units.
Transcribed Image Text:A ball of mass m = 5 kg is held motionless at t = 0 between two vertical springs. Both
springs have relaxed length Lo = 3 m. The springs connect to each other at the center of the
ball.
The spring on the bottom (orange) has its fixed end on the floor (at the origin of the coordinate
system), has stiffness k₁ 300 N/m, and is currently \textbf{compressed} to a length L₁ =
=
=
2.5 m.

The spring on the top (green) has its fixed end on the ceiling, has stiffness k2
100 N/m, and
is currently \textbf{stretched} to a length L2 = 4.5 m.
The ceiling is at a height h = L₁ + L2 = 7 m above the floor. Gravity points straight down.
