A toy car with mass 0.043 kg is propelled by a spring with spring constant 92 N/m onto a track. The track contains a vertical loop of radius 0.15 m. Ignore any losses due to friction and use g = 10 m/s2. What is the minimum compression of the spring necessary for the car to complete the loop...

the buoyant force: 362.6 the weight: mg=362.6 how do i figure out the tension in the string? is it the buoyant force - the weight of the cube

Well the forces acting on the cork are the buoyant force which is the the weight of the cork which is mg which is: BF= 3.7*g but gravity in SI units is 9.8kg/m^3 and I am using CGS units so gravity is 98g/cm^3 So the weight of the cork is BF= 3.7(98)=362.6 the buoyant force = to the...

okay, the density of an object is its mass divided by its volume: D=m/v so for the cube all i have in the equation is : D= 58g/v So i know that in order to get the density i need the volume of the cube. this is where i am stuck.

One end of a light thin string is attached to the bottom of a 3.7 g, 42 cm3 cork. The other end is attached to a 58 g cube. The arrangement is placed in water and it is found that with 82% of the cork submerged the cube is held in equilibrium. What is the density of the cube in g/cm3? I need...
