Solution
A small metal ball thrown vertically upwards from the top of a tower with an initial velocity of 20ms-1. If the ball took a total of 6s to reach ground level, determine the height of the tower [g = 10ms-2]
A
60m
B
80m
C
100m
D
120m
medium Difficulty
Verified Correct Answer: Option A
Physical Principles & Numerical Solution
Time from tower to top, t = \(\frac{u - v}{g}\)
= \(\frac{20 - 0}{10}\)
= 2s
distance from tower to top
x = ut - \(\frac{1}{2}\)gt2
= (20 x 2) - (\(\frac{1}{2}\) x 10 x 2 x 2)
= 20m
Time from the top to the ground, t = 6 - 2
= 4s
distance from top to ground,
x = ut - \(\frac{1}{2}\)gt2
= (0 x 4) + (\(\frac{1}{2}\) x 10 x 4 x 4)
= 80m
therefore, height of tower = 80 - 20
= 60m

Circular Motion, Gravitation & Simple Harmonic Motion
Solution
An object moves with uniform speed round a circle. Its acceleration has
A
constant magnitude and constant direction
B
constant magnitude and varying direction
C
varying magnitude but constant direction
D
varying magnitude and varying direction
medium Difficulty
Verified Correct Answer: Option B
Physical Principles & Numerical Solution
When an object moves with uniform speed in a circular path, its acceleration (centripetal acceleration) has a constant magnitude but changes direction continuously as the object moves around the circle. This acceleration is always directed towards the center of the circle.

Solution
A body of mass 100g moving with a velocity of 10.0ms-1 collides with a wall. If after collision, it moves with a velocity of 2.0ms-1 in the opposite direction, calculate the change in momentum.
A
0.8Ns
B
1.2Ns
C
12.0Ns
D
80.0Ns
medium Difficulty
Verified Correct Answer: Option B
Physical Principles & Numerical Solution
Initial momentum = 0.1 x 10 = 1Ns
final velocity = -2ms-1
Final momentum = -2 x 0.1 = -0.2Ns
Change in momentum = -0.2 - 1 = -1.2Ns

Solution
A wheel and axle have radii 80cm and 10cm respectively. If the efficiency of the machine is 0.85, an applied force of 1200N to the wheel will raise a load of
A
8.0N
B
6.8N
C
8160N
D
9600N
medium Difficulty
Verified Correct Answer: Option C
Physical Principles & Numerical Solution
Efficiency = m.A x \(\frac{1}{V.R}\) x 100%
85 = \(\frac{load}{1200}\) x \(\frac{10}{80}\) x \(\frac{100}{1}\)
load = 8160N

Solution
A 20kg mass is to be pulled up a slope inclined at 30o to the horizontal. If the efficiency of the plane is 75%, the force required to pull the load up the plane is [g = 10ms-2]
A
13.3N
B
73.5N
C
133.3N
D
53.2N
medium Difficulty
Verified Correct Answer: Option C
Physical Principles & Numerical Solution
Efficiency = m.A x \(\frac{1}{V.R}\) X 100%
75 = \(\frac{20 \times 10}{effort}\) x \(\frac{1}{\frac{g}{sin\theta}}\) x 100%
Effort = 133.3N

Solution
The spiral spring of a spring balance is 25.0cm long when 5N hangs on it and 30cm long, when the weight is 10N. What is the length of the spring if the weight is 3N assuming Hooke's law is obeyed?
A
15.0cm
B
17.0cm
C
20.0cm
D
23.0cm
medium Difficulty
Verified Correct Answer: Option D
Physical Principles & Numerical Solution
let the length be Lcm
\(\frac{5 - 3}{25 - L}\) = \(\frac{10 - 5}{30 - 25}\)
L = 23cm
