A car traveling at 7.0 m/s acceleartes uniformly at 2.5 m/s2 to reach a speed of 12.0 m/s. How long does it take for this acceleration to occur?
We can use the formula Vf=Vi+at (final velocity=initial velocity + acceleration * time)
Plug in the numbers: 12.0=7.0+2.5t
Subtract both sides by 7: 5=2.5t
Final answer: t=2 seconds
