If 84 J of work are exerted to pull a wagon, how much force does it take to pull the wagon 7. 0 m? Round your answer to the nearest whole number. It takes N of force to pull the wagon.

The force required to pull a wagon if 84 J of work are exerted to pull a wagon 7m is 12 Joules.

HOW TO CALCULATE WORK DONE:

Work done can be calculated by multiplying the force applied on an object by the distance traveled. That is;

Work done = Force × distance

Force = Work done ÷ distance

According to this question, the work done is 84J and the wagon was pulled to a distance of 7 metres. The force is calculated as follows:

Force = 84J ÷ 7m

Force = 12N.

Therefore, the force required to pull a wagon if 84 J of work are exerted to pull a wagon 7m is 12 Joules.

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
