a bus is moving at a speed of 18 km/h. it is retarding at a rate of 2

1.	a bus is moving at a speed of 18 km/h. it is retarding at a rate of 2 m/s^2 and comes to rest finally. find the distance travelled by it.
Answer» Given INITIAL VELOCITY=18km/h=18*5/18 =5m/sec FINAL velocity= 0 RETARDATION = -2m/sec SQUARE Distance= ? ${v}^{2} = {u }^{2} + 2as$ ${0}^{2} = {5}^{2} + 2( - 2)(s)$ 0=25-4s 25 =-4s 25/-4=s 6.25=s Distance= 6.25m

Answer»

Given

INITIAL VELOCITY=18km/h=18*5/18

=5m/sec

FINAL velocity= 0

RETARDATION = -2m/sec SQUARE

Distance= ?

${v}^{2} = {u }^{2} + 2as$

${0}^{2} = {5}^{2} + 2( - 2)(s)$

0=25-4s

25 =-4s

25/-4=s

6.25=s

Distance= 6.25m
