Answer:
, it will sink
Explanation:
The density of an object is given by

where
m is the mass of the object
V is its volume
For the body in the problem, we have
m = 4 kg = 4000 g

Therefore, its density is

And the object will sink in water, because its density is larger than that of water, which is
. (an object sinks when its density is larger than that of water, otherwise it floats).

Answer:
first one i think is this. work = 1/2 kx^2 = 1/2 Fx
2nd, is 0.08 J
Explanation:
EE = ½ kx²
EE = ½ (400 N/m) (0.02 m) ²
EE = 0.08.
THIRD, Velocity of the stone is 4 m/s when it leaves catapult.
