A block of wood of mass 10.8 kg and density 4.42 x 102 kg/m3, floats on water. (a) What is the minimum amount of aluminum (density 2.70 x 103 kg/m3) that can be placed on top of the wood block and cause the block of wood and the aluminum to sink? (b) If instead it was a block of ice of mass 10.8 kg and density 8.90 x 102 kg/m3. What is the minimum amount of aluminum that can be...

a) A block of Aluminum has a density of 2700 kg/m^3 and a mass of 63 grams. The block is tied to one end of a string and the other end of the string is tied to a force scale. The block is allowed to hang in the air from the string. Calculate the force which will be registered on the scale. b) The block remains tied to the string but is now completely submerged in a container of water....

A block of mass 2 kg and a block of mass 3 kg are sliding on...

A block of mass 2 kg and a block of mass 3 kg are sliding on a frictionless surface. They collide and stick together. Before the collision the first block was travelling at 5 m/s in the positive x direction. After the collision the two blocks are travelling at 6 m/s in the negative x direction. What was the x component of the velocity of the second block before the collision?

A cubical block of wood 0.100 m on a side and with density of 550 kg/m3 floats in a jar of water. Oil with a density of 750 kg/m3 is poured on the water until the top of the oil layer is 0.035 m below the top of the block. a) How deep is the oil layer? b) What is the gauge pressure at the block’s lower face?

A thin block of soft wood with a mass of 0.078 kg rests on a horizontal frictionless surface. A bullet with a mass of 4.67 g is fired with a speed of 601 m/s at a block of wood and passes completely through it. The speed of the block is 21 m/s immediately after the bullet exits the block. (a) Determine the speed (in m/s) of the bullet as it exits the block. m/s (b) Determine if the final kinetic...

A block of wood of mass 4 kg is connected to a spring, whose other end is tethered to a wall. As the spring is stretched and compressed, the block undergoes simple harmonic motion on the (frictionless) floor. The displacement of the block with respect to its equilibrium position is x = 0.205 cos ( 22.5 t ) where x is measured in m and t is measured in seconds. 1.) Which of these statements is true at time t...

1.A bullet with a mass of 45 g is fired into a 8.3-kg block of wood resting on a floor against a spring. This ideal spring (k = 76 N/m) has a maximum compression of 28 cm. What was the initial speed of the bullet? 2.Two common and identical carts are used to perform an experiment. Cart A is pushed toward the stationary cart B with a velocity of 2.6 m/s. After the collision, cart A bounces back with a...

Block A in the figure below has mass 1.30 kg , and block B has mass 2.85 kg . The blocks are forced together, compressing a spring S between them; then the system is released from rest on a level, frictionless surface. The spring, which has negligible mass, is not fastened to either block and drops to the surface after it has expanded. Block B acquires a speed of 1.20 m/s . Part A What is the final speed of...
