A car accelerates from rest at 2.0 m/s2 over a distance of 25 m.
Use the equation: (final velocity)2−(initial velocity)2=2×acceleration×distance(\text{final velocity})^2 - (\text{initial velocity})^2 = 2 \times \text{acceleration} \times \text{distance}(final velocity)2−(initial velocity)2=2×acceleration×distance
What is the final velocity of the car?
7.1 m/s7.1\ \text{m/s}7.1 m/s
10 m/s10\ \text{m/s}10 m/s
50 m/s50\ \text{m/s}50 m/s
100 m/s100\ \text{m/s}100 m/s
