Question

A bus starts frim rest and picks up a velocity of 60 m/s in 30 seconds.Calculate the uniform acceleration of the bus in m/s^2​

Answer 1

Answer:

Explanation:

Answer

a=0.1m/s  

2

 

and t=2min=120s

(A)v=u+at=0+0.1×120

⟹v=12m/s

(b)s=ut+

⟹s=0+

​  

×0.1×(120)  

2

 

⟹s=720m

Answer 2

Answer:

u = 0

v = 90kmph = 90 x 5/18 = 25 m/s

t = 30 s

a = v - u / t

a = 25-0/30

a = 5/6 = 0.833 m/s²
