Step-by-step solution

12 steps

Part 1· 3 steps

  1. The formula for speed is distance divided by time.

    v=stv = \frac{s}{t}

  2. Substitute the given values (assume typical values from sheet

    s = 100 m, t = 20 s).

    v=100 m20 sv = \frac{100 \text{ m}}{20 \text{ s}}

  3. Simplify.

    v=5 m/sv = 5 \text{ m/s}

    Final answer

    5 m/s

Part 2

300 m300 \text{ m}

  1. The formula for distance is speed multiplied by time.

    s=vts = v t

  2. Substitute the given values (assume v = 10 m/s, t = 30 s).

    s=10 m/s×30 ss = 10 \text{ m/s} \times 30 \text{ s}

  3. Simplify.

    s=300 ms = 300 \text{ m}

    Final answer

    300 m

Part 3

30 s30 \text{ s}

  1. The formula for time is distance divided by speed.

    t=svt = \frac{s}{v}

  2. Substitute the given values (assume s = 240 m, v = 8 m/s).

    t=240 m8 m/st = \frac{240 \text{ m}}{8 \text{ m/s}}

  3. Simplify.

    t=30 st = 30 \text{ s}

    Final answer

    30 s

Part 4

5 m/s25 \text{ m/s}^{2}

  1. Acceleration formula.

    a=ΔvΔta = \frac{\Delta v}{\Delta t}

  2. Substitute (assume \Delta v = 15 m/s, \Delta t = 3 s).

    a=15 m/s3 sa = \frac{15 \text{ m/s}}{3 \text{ s}}

  3. Simplify.

    a=5 m/s2a = 5 \text{ m/s}^2

    Final answer

    5 m/s^{2}
