Question

A box is loaded on open horizontal floor of truck. The coefficient of friction between the box and floor is 0.6. The
maximum magnitude of acceleration of truck so that the box does not slip back is (g= 10 m/s2)
0 1 m/s2
o 3 m/s2
o 6 m/s2
O 2 m/s2​

Answer 1

$\bold\red{Answer }$

6m/s2 is the answer of this question ok

Answer 2

Answer:

$a=6ms^{-2}$

Explanation:

From the Question,

Given That,

The coefficient of friction between the box and floor is 0.6.

$F= \mu.N, (N=mg)\\\\F= \mu.mg\\\\and\\\\F=ma$

The maximum magnitude of the acceleration of the truck so that the box does not slip back means both forces are equal.

$\mu.mg=ma\\\\\mu.g=a\\\\0.6X10=a\\\\a=6ms^{-2}$

Hence, The maximum magnitude of the acceleration of the truck so that the box does not slip back is $a=6ms^{-2}$.
