if it is further continued, the acceleration attained by the body in
2
ms
−
is___ (
2

)

Answer 1

The coefficients of static and dynamic friction are 0.7 and 0.4. The

minimum force required to create motion is applied on a body and

if it is further continued, the acceleration attained by the body in

2

ms

−

is___ (

2

g m s =10 /

)

Answer 2

the answer is

($mew_{s}$-$mew_{k}$)g=a

(0.7-0.4)10=a

0.3*10=a

$3ms^{-2}$
