A5kg block is pulled across a table by a horizontal force of 40 n with a frictional force of 8 n opposing the motion. draw a force diagram and determine the net force. then calculate the acceleration of the object.

Net force on the block is 32 N.

Acceleration of the object is 6.4 m/s².

Explanation:

Let the acceleration of the object be m/s².

Given:

Mass of the block is,

Force of pull is,

Frictional force on the block is,

The free body diagram of the object is shown below.

From the figure, the net force in the forward direction is given as:

Now, from Newton's second law of motion, net force is equal to the product of mass and acceleration. So,

Therefore, the acceleration of the object in the forward direction is 6.4 m/s².

electromagnetic waves travel through space with vacuums. give me brainliest if right.

an energy transformation flow diagram is shown

where is it ?
