Ha it’s not spring break yet for me but if it is for you I hope you have a good spring break as well :)
Answer:
1.315 m
Explanation:
Assumption: there is no resistance of any type
v= 5.08 m/s
g = 9.81m/s^2
change in kinetic energy = change in gravitational potential energy
mass on both side is same so it cancels out
and also making 'h' alone on one side
h= ((5.08)^2)/(2*9.81)
h =1.3153m
Answer:
The object with a higher mass has three times the kinetic energy of the less massive object.
We know that K.E.= 1/2 mv²
mass of first object = 1kg
speed = v
So K.E. = 1/2mv²
= 1/2 × (1) × v²
=
Now the mass of second body = 3kg
speed = v
So K.E. = 1(3)v²/2
=
now
K.E of first / KE of 2nd

Please see the file attached
take the difference of water levels to find volume of the ring. convert ml to cm3. multiply by density to cancel out cm3 units (idk how to explain that well). you get 8.4g
