A solid steel sphere of radius 1.50cm and density of 8045 kg/m³ was launched on a horizontal frictionless surface. The sphere was launched using a spring gun which possessed a spring with a force constant of 35.6 N/m. The spring was compressed 30.0 cm and the sphere was launched. At the end of the frictionless surface (that was 0.955 m above the floor), the sphere rolled (no slipping) up a 25° ramp with height of 1.15m and then launched off of the ramp. The coefficient of rolling friction between the sphere and ramp was 0.0500. What was the speed of the sphere at the end of the frictionless surface (when it was sliding - not rolling) ? What was the translational speed of the sphere at the very beginning of the ramp (when it transitioned to perfect rolling (no slipping))? What was the sphere's rotational speed (in revolutions per minute) at the very top of the ramp? Ignoring drag, at what horizontal distance from the end of the ramp did the sphere strike the floor? What was the greatest height the sphere achieved (above the floor)?

A bubble is sphere with 10 mm radius and a density of 1.0
kg/m^3.
This goes up in a glass of water which has Pwater=0.95
g/cm^3.
It starts at the bottom of a glass which is 10 cm tall.
Cd=0.8
Hypothesize how long it would take the bubble to rise to the top
of the glass.
Draw a complete force diagram of the bubble, including weight,
buoyancy and drag forces. Make sure your coordinate axis points in
the direction of...

A solid, homogeneous sphere with a mass of m0, a
radius of r0 and a density of ρ0 is placed in
a container of water. Initially the sphere floats and the water
level is marked on the side of the container. What happens to the
water level, when the original sphere is replaced with a new sphere
which has different physical parameters? Notation: r means the
water level rises in the container, f means falls, s means stays
the same....
