Ahorizontal clothesline is tied between 2 poles, 16 meters apart. when a mass of 3 kilograms is tied to the middle of the clothesline, it sags a distance of 3 meters. what is the magnitude of the tension on the ends of the clothesline? note: use g=9.8m/s2 for the gravitational acceleration.

Which of the following best describes the circuit shown below?

Agust of wind pushes a beach ball with a force of 9 newtons. the ball rolls 10 meters in 3 seconds. what is the power of the wind? 900 w 90 w 30 w 3 w

A60-kg box is being pushed a distance of 6.8 m across the floor by a force p with arrow whose magnitude is 162 n. the force p with arrow is parallel to the displacement of the box. the coefficient of kinetic friction is 0.24. determine the work done on the box by each of the four forces that act on the box. be sure to include the proper plus or minus sign for the work done by each force. (the floor is level and horizontal. forces that act on the box: pushing force p, frictional force f, normal force n, and weight mg.)
