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...

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 floating ball has a density (P») of 600 kg/m' and has a radius (R) of 0.055 m. The equation that gives the depth (x) to which the ball is submerged under water with a density (Pw) of 1000 kg/m is given by:4 4/3*pi*R^3*pb*g=pi*x^2(R_x/3)*Pw*g where the gravitational acceleration g = 9.81 m/s. R a) Use the false-position method to find the depth x to which the ball is submerged under water within an interval [0, 0.1]? Conduct three iterations only...
