Answer to a math question If the speed of a bicycle changes until it reaches a speed of 8m/s in 20 seconds with an acceleration of 0.3m/s²
Calculate its original speed
1. Write the kinematic equation: v_f = v_i + a \cdot t
2. Rearrange to solve for v_i: v_i = v_f - a \cdot t
3. Substitute the given values: v_i = 8 - (0.3 \cdot 20)
4. Calculate the result: v_i = 8 - 6 = 2 \, \text{m/s}
5. The original velocity is v_i = 2 \, \text{m/s}
