A scuba diver is in a freshwater lake with water of density 1000 kg/m^3. To have neutral buoyancy, she has to wear a weight belt that has a mass of 8 kg. If she and the rest of her gear had a total mass of 65 kg before putting on the weight belt, what is her total volume in liters? 1m^3= 1000L.

Ben(55 kg) is standing on very slippery ice when junior(25kg) bumps into him. junior was moving at a speed of 8m/s before the collision and ben and junior embrace after the collision. find the speed of ben and junior as they move across the ice after the collision .

Ablock of mass m slides on a horizontal frictionless table with an initial speed v0 . it then compresses a spring of force constant k and is brought to rest. the acceleration of gravity is 9.8 m/s2. how much is the spring compressed x from its natural length? 1) x = v0*sqrt(k/(mg)) 2) x=v0*sqrt(m/k) 3) x=v0*((mk)/g) 4) x=v0*sqrt(k/m) 5) x=v0*(m/kg) 6) x=v0*sqrt((mg)/k) 7) x=(v0)^2/(2g) 8) x=v0*(k/(mg)) 9) x=(v0)^2/(2m) 10) x=v0*((mg)/k)

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
