- For 1a: Draw a horizontal line at v = 10 m/s from t = 0 to t = 10 s. Label the y-axis "velocity in ms⁻¹" and x-axis "time in s". Number the axes appropriately.
- For 1b: Draw a straight line starting at (0, 0) and ending at (15, 20). Label the y-axis "velocity in ms⁻¹" and x-axis "time in s". Number the axes appropriately.
- For 1c: Draw a straight line starting at (0, 30) and ending at (5, 10). Label the y-axis "velocity in ms⁻¹" and x-axis "time in s". Number the axes appropriately.
- For 2a: Acceleration = (20 - 0) / (10 - 0) = 2 m/s².
- For 2b: Acceleration = (24 - 8) / (16 - 0) = 1 m/s².
- For 2c: Acceleration = (0 - 15) / (25 - 0) = -0.6 m/s².
- For 4a: Distance = area of rectangle = 2 × 10 = 20 m.
- For 4b: Distance = area of trapezoid = (1/2) × (10 + 18) × 50 = 700 m.
- For 4c: Distance = area of trapezoid = (1/2) × (16 + 24) × (20 + 5) = 500 m.
