(i) Uniform acceleration is a constant time rate of increase in velocity.
(ii) Linear velocity = angular velocity x radius of path V = \(\omega\)r~(b) Scale: 1 cm to 5 N
30N = 6cm and 40N = 8cm

(c) A floating ship is balanced by its weight and the upthrust on it. Hence when off-loaded the upthrust becomes greater than the weight of the ship, therefore when refilled with sand and water, equilibrium is restored for stability.

d)(i) \(\mu = tan \theta = tan 30^o = 0.5774\)
(ii) F = \(\mu g cos \theta\) = 0.5774 x 20 x 10 x Cos 30\(^o\) = 100N
