Q6. A lead bullet of mass 0.05 kg is fired with a speed of 200 m s⁻¹ into a lead block of mass 0.95 kg at rest. Given that the lead block moves after the impact, determine its kinetic energy after impact
A50 J
B100 J
C150 J
D200 J
Correct Answer: A
Inelastic collision (same material): momentum conserved, v = (0.05 × 200) / 1 = 10 m/s. KE = ½ × 1 × 10² = 50 J.

Q8. The equation of a wave traveling along the positive x-direction is given by: y = 0.25 × 10⁻³ sin(500t - 0.025x). Determine the angular velocity of the wave motion.
A0.25 × 10⁻³ rad s⁻¹
B0.25 × 10⁻¹ rad s⁻¹
C5.00 × 10² rad s⁻¹
D2.50 × 10³ rad s⁻¹
Correct Answer: C
Given wave equation:
y = 0.25 × 10⁻³ sin(500t - 0.025x)
Standard form of wave equation:
y = A sin(ωt - kx)
where:
A = amplitude
ω = angular velocity (angular frequency)
k = wave number
t = time
x = position
Comparing the given equation with standard form:
y = 0.25 × 10⁻³ sin(500t - 0.025x)
y = A sin(ωt - kx)
Identifying parameters:
Amplitude (A) = 0.25 × 10⁻³ m
Angular velocity (ω) = 500 rad/s
Wave number (k) = 0.025 rad/m
Converting to scientific notation:
ω = 500 rad/s = 5.00 × 10² rad s⁻¹
