Question

5 l A bus starts from west and attains a velocity of 72 kkal
Rm ich is too 10 sec . Find !alunds travelled , &
locite)​

Answer 1

Answer:

Initial velocity (u) = 0m/s

Final velocity (v) = 72 km/hr = 72 x 5/18 =  20m/s

time (t) = 10 seconds

acceleration (a) = ??

distance??

v = u + at

20 = 0 + a (10)

10a = 20

a = 20/10

a = 2m/s²

$s = ut + \frac{1}{2} at^{2}$

$s = 0 (10) + \frac{1}{2} (4) (10)^{2}$

$s = 2X100$

s = 200m
