6. A car slows from 22m/s to 3m/s with a constant acceleration of -2.1m/s². How long does this require? 7.A race car travelling at +44m/s is uniformly accelerated to a velocity of +22m/s over an 11s interval. What is its displacement during this time? 8.A rocket travelling at +88m/s is accelerated to +132m/s over a 15s interval. What is its displacement during this time? 9.A car accelerates at a constant rate from 15m/s to 25m/s while it travels 125m. How long (in seconds) does this motion take?
