PHYSICS FINAL EXAM 2027 WITH CORRECT
ANSWERS AND MULTIPLE QUESTIONS
1. A car accelerates from rest at 3 m/s² for 5 seconds. What
is its final velocity?
A) 5 m/s
B) 15 m/s
C) 8 m/s
D) 0.6 m/s
Correct Answer: B
Rationale: v = u + at = 0 + (3)(5) = 15 m/s.
2. A 2 kg ball is dropped from a height of 20 m. Ignoring air
resistance, what is its speed just before impact? (g = 10 m/s²)
A) 10 m/s
,Page 2 of 148
B) 20 m/s
C) 14.1 m/s
D) 400 m/s
Correct Answer: B
Rationale: v² = u² + 2gh = 0 + 2(10)(20) = 400 → v = 20
m/s.
3. A force of 10 N acts on a 5 kg object. What is its
acceleration?
A) 0.5 m/s²
B) 2 m/s²
C) 50 m/s²
D) 15 m/s²
Correct Answer: B
Rationale: a = F/m = 10/5 = 2 m/s².
4. Scenario: A 60 kg astronaut in space pushes off a 120 kg
satellite with a force of 300 N for 0.2 seconds. What is the
astronaut’s final velocity?
,Page 3 of 148
A) 0.5 m/s
B) 1.0 m/s
C) 2.0 m/s
D) 0 m/s
Correct Answer: B
Rationale: Impulse = FΔt = 300 × 0.2 = 60 N·s = Δp = mΔv
→ Δv = = 1.0 m/s.
5. Two masses 3 kg and 6 kg are 2 m apart. Gravitational
force between them? (G = 6.67×10⁻¹¹ N·m²/kg²)
A) 3.0×10⁻¹⁰ N
B) 2.0×10⁻¹⁰ N
C) 1.5×10⁻¹⁰ N
D) 3.0×10⁻⁹ N
Correct Answer: A
Rationale: F = G m₁m₂/r² = (6.67e-11)(3×6)/4 = (6.67e-
11×18)/4 = 3.0×10⁻¹⁰ N.

6. A 500 g object has kinetic energy 100 J. Its speed is:
A) 10 m/s
B) 14.14 m/s
C) 20 m/s
D) 200 m/s
Correct Answer: C
Rationale: KE = ½ mv² → 100 = ½ (0.5) v² → 100 = 0.25 v²
→ v² = 400 → v = 20 m/s.
7. Scenario: A roller coaster car (500 kg) at height 30 m has
speed 10 m/s. Total mechanical energy? (g = 10 m/s²)
A) 150,000 J
B) 175,000 J
C) 200,000 J
D) 125,000 J
Correct Answer: B
Rationale: PE = mgh = 500×10×30 = 150,000 J. KE =
½×500×100 = 25,000 J. Total = 175,000 J.
