# Blocks with masses of are lined up in a row on a frictionless table. All three are pushed forward by a force applied to the block. a. How much force does the block exert on the block?b. How much force does the block exert on the block?

a. The block exerts a force of on the block.

b. The block exerts a force of on the block.

See the step by step solution

## Part (a) Step 1 : Given information

Three blocks of are lined up in a row on a frictionless table. All three are pushed forward by a force applied to the block.

## Part (a) Step 2 : Calculation

The force applied on the blocks is and the acceleration of the total system due to all masses is given by :-

The must push on the block hard enough to accelerate it at and Force on 3 kg is given by :-

## Part (a) Step 3 : Final answer

The block exerts a force of on the block.

## Part (b) Step 4 : Given information

Three blocks of are lined up in a row on a frictionless table. All three are pushed forward by a force of applied to the block.

## Part (b) Step 5 : Calculation

The total force on the block would be . here force 'F' is the force block exerted on the block in backward direction.

Net force on 1 kg is given by :-

## Part (a) Step 6 : Final answer

The block exerts a force of on the block.
