Question

a bus starting from rest moves with a uniform acceleration of 0.1m powersec -2for 2min. find the speed acquired the distance travelled

Answer 1

$\sqrt[2]{5}$

Answer 2

Hi Friend

As per the question various quatities are given

t= 120 sec

a= 0.1 m^s2

u= 0 m/s

v= ?

s=?


Using equation

v= u+ at

v= 0+ 0.1 ×120

v= 12 m/s


Using Second equation of motion

v^2- u^2 = 2as
v ^2 -0 =2as

(12)^2= 2×0.1×s

s= 720 m


Hence distance covered is 720 metre.
