Question

A bus travels at a constant speed of 32m/s for 5 seconds. It begins to accelerate at a rate of 3m/s^2 for 7 seconds and then maintains that speed for another 18 seconds. Finally, it slows down to rest in 22 seconds. How far did the bus travel during the course of this entire problem?

Answer 1

solution L. van travels at constant speed of 32 m/ for 5 seconds. then traveled distance - 3245 160m 2. After this, van begins to accelerate at a rate of 3m/s2 for 7 seconds. then traveled distance Sz: ut + fat? = 32x7+ & * 3872 52 : 297.5 m firal speed v= ut at - 32 + 3x7 53 mis at a speed of 53m/s 3. After this, van travels for 10 seconds then traveled distance Sy : 53 x 1d 53 = 954 m)

4. Finally, down to rest in 22 seconde then V: Utat 0:53 + 2x22 and proveled disfarce S4 = at that? = 53 ¥?? - { * 5 * 22x22 22 14 = 583 m 7 Нег се, tot al distance traveled by von during the course of this entire problem s=s, the tsatse 1607297.5 954 + 583 I s 1994.5 m Ans
