1A particle moves in a straight line with constant acceleration 3 m/s² from rest. What is its speed after 4 s?
A.12 m/s
B.7 m/s
C.3 m/s
D.48 m/s
Explanation: Use v = u + at with u = 0, a = 3 m/s² and t = 4 s: v = 0 + 3 × 4 = 12 m/s.
2A particle starts with speed 8 m/s and accelerates at 2 m/s² for 5 s. How far does it travel in that time?
A.65 m
B.50 m
C.40 m
D.90 m
Explanation: s = ut + (1/2)at² = 8×5 + (1/2)×2×5² = 40 + 25 = 65 m.
3A car slows from 20 m/s to 8 m/s in 6 s with constant acceleration. Taking the direction of the initial velocity as positive, what is the acceleration?
A.-2 m/s²
B.2 m/s²
C.-12 m/s²
D.4 m/s²
Explanation: a = (v − u)/t = (8 − 20)/6 = −12/6 = −2 m/s².
4On a velocity–time graph, a straight line runs from (0 s, 0 m/s) to (10 s, 20 m/s). What is the constant acceleration?
A.2 m/s²
B.0.5 m/s²
C.20 m/s²
D.200 m/s²
Explanation: Acceleration is the slope of the v–t graph: a = Δv/Δt = 20/10 = 2 m/s².
5A particle starts from rest and accelerates at 4 m/s² over a distance of 18 m. Using v² = u² + 2as, what is its final speed?
A.12 m/s
B.6 m/s
C.√18 m/s
D.72 m/s
Explanation: v² = 0 + 2(4)(18) = 144, so v = 12 m/s (taking the positive root for speed).
6A particle has displacement s = 3t² − 2t (s in metres, t in seconds). What is its velocity at t = 2 s?
A.10 m/s
B.8 m/s
C.12 m/s
D.4 m/s
Explanation: v = ds/dt = 6t − 2. At t = 2, v = 12 − 2 = 10 m/s.
7Take g = 10 m/s². A stone is dropped from rest from a height of 45 m. How long does it take to reach the ground?
A.3 s
B.4.5 s
C.9 s
D.√45 s
Explanation: s = (1/2)gt² with u = 0: 45 = 5t² ⇒ t² = 9 ⇒ t = 3 s.
8A projectile is launched with speed 20 m/s at 30° above the horizontal. Take g = 10 m/s². What is the initial vertical component of velocity?
A.10 m/s
B.20 m/s
C.10√3 m/s
D.20√3 m/s
Explanation: u_y = u sin θ = 20 sin 30° = 20 × 0.5 = 10 m/s.
9For a launch of 20 m/s at 30° (g = 10 m/s²), what is the initial horizontal component of velocity?
A.10√3 m/s
B.10 m/s
C.20 m/s
D.5 m/s
Explanation: u_x = u cos θ = 20 cos 30° = 20 × (√3/2) = 10√3 m/s.
10A force of 15 N acts on a particle of mass 3 kg. Ignoring all other forces, what is the magnitude of the acceleration?
A.5 m/s²
B.45 m/s²
C.0.2 m/s²
D.18 m/s²
Explanation: Newton’s second law: F = ma ⇒ a = F/m = 15/3 = 5 m/s².
