Q1Forces and EquilibriumNewton's Laws of MotionFree sample

A block is at rest on a rough horizontal plane. The coefficient of friction between the block and the plane is $1.25$ .

(i)

State, giving a reason for your answer, whether the minimum vertical force required to move the block is greater or less than the minimum horizontal force required to move the block.

(ii)

A horizontal force of continuously increasing magnitude $P\text{ N}$ and fixed direction is applied to the block.

Given that the weight of the block is $60\text{ N}$ , find the value of $P$ when the acceleration of the block is $4\text{ m s}^{-2}$ .
