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.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
