A crane lifts the 18,000kg steel hull of a ship out of the water. The density of steel is known to be 7.8 x 103 kg/m3, while that of water is 1000 kg/m3. A) While the steel hull is fully submerged in the water, what is the volume of water displaced by the hull? I really have no idea how to...

So for B: Energy - Friction= 75-12.99 = 62.01For C: Would I use the new energy 62.01/ (.75) = 86.68N

UPS delivery man is loading his truck by shoving the parcels up a ramp. The ramp is inclined at an angle of 30 degrees above the horizontal. He sends a parcel of mass 15 kg, up this ramp. the coefficient of sliding friction is .10 and gravitational force is class standard (10). A The...

So would I use: (Vf)^2 = (Vxo)^2 + 2(Ax) (Displacement) 0-36.8^2 = 10 (Displacement) 1354.24/10 = Displacement = 135.42 m

Stunt driver hired to do a scene where a motorcycle speeds horizontally off a 30m high cliff. There's a soft landing pad located 90m from the base. Ignore air resistance. (A) How fast must he go land on the soft padding? (B) the motorcycle has an acceleration of 5 m/s^2 on a dry road surface, he...
