Question
For #17 the answer is C, please explain why The cart of mass 10 kg shown above moves without frictional loss on a level table. A 10 N force pulls on the cart horizontally to the right. At the same time, a 30 N force at an angle of 60 degree above the horizontal pulls on the cart to the left. Which of the following describes a manner in which this cart could be moving? Select two answers. moving left and speeding up moving left and slowing down moving right and speeding up moving right and slowing down Two people are pulling on the ends of a rope. Each person pulls with a force of 100 N. The tension in the rope is: 0 N 50 N 100 N 200 N The parabola above is a graph of speed v as a function of time t for an object. Which of the following graphs best represents the magnitude F of the net force exerted on the object as a function of time t?Explanation / Answer
17
as the rope is pulled by applying force 100 N at one end , the rope pulls it back with the same force 100 N as per newton's third law. This is the reson that the tension in the rope is 100 N.
