Question

a block of metal is lying on the floor of a bus. the maximum acceleration which can be giveeto the bus so that the block may remain at rest will be

Answer 1

Answer:

Explanation:

F = fs

<= µs N

ma <= µs (mg)

a <= µs g

Maximum value of acceleration occurs at equal to condition. Hence, amax = µs g gives the maximum acceleration which can be given to the bus so that the block remains at rest.

Answer 2

Explanation:

F = fs  <= µs N

ma <= µs (mg)

a <= µs g

Maximum value of acceleration occurs at equal to condition.

Hence, acc max = µs g gives the maximum acceleration which can be given to the bus so that the block remains at rest
