Answer

C) v_{f}=v_{i}+at Explanation 1. Identify the known variables Initial velocity v_i = 5.94 \, m/s, acceleration a = 2.76 \, m/s^2, time t = 1.38 \, s. 2. Determine the appropriate formula To find final velocity v_f, use **v_{f} = v_{i} + at** which directly relates initial velocity, acceleration, and time to final velocity.

Explanation

1. Identify the known variables<br /> Initial velocity $v_i = 5.94 \, m/s$, acceleration $a = 2.76 \, m/s^2$, time $t = 1.38 \, s$.<br />2. Determine the appropriate formula<br /> To find final velocity $v_f$, use **$v_{f} = v_{i} + at$** which directly relates initial velocity, acceleration, and time to final velocity.
