Tue roblem A poorly tuned Yugo can accelerate from rest to a speed of 30 m/s in 20 s. a) What is the average acceleration ofthe car? b) What distance does it trave! in this time?
At t = O a car has a speed of 30 m/s. After 5 s, its speed is 15 m/s.
What is its average acceleration during this time interval?
A bear spies some honey and takes off from rest, lmnbering along at a constant velcoity of 5 m/s towards the honey. If the honey is 15 meters away how long does it take him to get tao it?
A bus moving at 20 m/s (t = O) slows at a rate of 4 m/s each second.
a) How Jong does it take the bus to stop?
b) How far does it trave! while braking?
