Question

SIMPLE QUESTIONS FOR YOU ALL
A bus was moving at a speed of 54 km/h. on applying brakes, it stopped in 8 seconds. calculate the speed acquired and distance traveled in this time.

Answer 1

The speed acquired is 0m/s

Answer 2

Speed acquired?????

Answer 3

Because the bus stopped

Answer 4

That be zero, since it stops!

Answer 5

plzzz do show u r solutions

Answer 6

distance use, x = v=0.5(u+v)t

Answer 7

give answer in one comment please its my request

Answer 8

So x = 0.5* 15 * 8 = 60m

Answer 9

Well, you have initial velocity = u = 54 kmph = 54 x (5/18) m/sec = 15 m/sec
Final velocity = v = 0
Time = 8 seconds.

Use Newton Unkle's equation # 1 ---> \( a = \frac{v-u}{t}\), and fond out the deceleration 'a'.

Then, use \(v^2 - u^2 = 2as\) to find out the distance covered, i.e. 's'.

Answer 10

(Note of precaution: Newton's equations are only valid for uniform-linear motion, as you may know.)

Answer 11

sry...
use \[x=\frac{v+u}{2} \times t\]

Answer 12

thanks aproov it proved my solution was wrong

Answer 13

where v is final speed=0
u is initial speed=15
and t=8

Answer 14

Yeah, using the average velocity funda is good actually, @King

Answer 15

oKAY thanks king to u as well

Answer 16

In fact innovative. :]

Answer 17

yw...thnx @apoorvk

Answer 18

lol
