(a(i))[2]
Calculate the height $h$ of the cylinder.
(a(ii))[2]
Show that the upthrust on the cylinder is $0.39\,\text{N}$.
(a(iii))[1]
Calculate the tension $T$ in the string.
(b(i))[2]
Use Fig. 2.2 to find the acceleration of the cylinder at time $t = 2.0\,\text{s}$.
(b(ii))[2]
The top face of the cylinder is $0.32\,\text{m}$ below the water surface at time $t = 0$. Use Fig. 2.2 to determine the depth of the top face below the surface of the water at time $t = 4.0\,\text{s}$.
(c(i))[1]
State the name of the force that acts on the cylinder when it is moving and does not act on the cylinder when it is stationary.
(c(ii))[2]
State and explain the variation, if any, of the acceleration of the cylinder as it falls downwards through the water.
