1. Write the kinematic equation: v_f = v_i + a \cdot t
2. Rearrange to solve forv_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 isv_i = 2 \, \text{m/s}
2. Rearrange to solve for
3. Substitute the given values:
4. Calculate the result:
5. The original velocity is
