A car slows down uniformly from a speed of 18.0 m/s to rest in 5.00 s. How far did it travel in that time?
What will be an ideal response?
Answer:
Applying v = u+ at where u is initial velocity and v is final velocity, a is acceleration and t is time.
Hence acceleration is -18/5 = -3.6 m/sec^2.
Now v^2 - u^2 = 2aS
Hence S = u^2/2a = 324/7.2 = 45 meters.
