QUESTION TWO
A person in a kayak starts paddling, and it accelerates from 0 to 0.8 mile/hour in a
distance of 0.8km. If the combined mass of the person and the kayak is 80kg, what
is the magnitude of the net force acting on the kayak?
QUESTION THREE
Discuss three (3) applications and limitations of dimensional analysis?
QUESTION FOUR
State the principle of homogeneity of dimensions?
QUESTION FIVE
A. A value of the acceleration of free fail g was determined by measuring the period
of oscillation T of a simple pendulum of length l. The relation between g, T and
l is given by:
? = 4?(? /?2)
In the experiment, l was measured as 0.55±0.02 m and T was measured as
1.50±0.02 s. Find the:
i. Value of g
ii. Uncertainty in the value of g
B. (a) State newton’s second law of motion and write an equation.
(b)Define the term INERTIA.
(c) Define impulse and write the equation.
