Question

3. A car starts moving along a line, first with an acceleration a = 5 m s? starting from rest,
then uniformly and finally decelerating at the.same rate, comes to rest in the total time of 2 25 seconds (t), then average velocity during the
time is equal to v = 72 kmph. How long does the particle move uniformly?​

Answer 1

Answer:

A car starts moving along a line, first with an acceleration a=5 ms−2 starting from rest, then uniformly and finally decelerating at the same rate, comes to rest in the total time of 25 seconds(t1), then average velocity during the time is equal to v=72 kmph. How long does the particle move uniformly?
