Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Question

A lazy fish sees your fishing hook. The fish is initially located at position (3 m,-2 m) and
drifts towards the fishing hook that is located at position (6 m, 0 m). The fish is a real lunker and
has a mass of m = 9.1 kg.
a) What is the displacement vector for the fish during this
time interval? Express your answer using unit-vector
notation (i.e. ->Ar = _î + __j)
(6 m, 0 m)
|(3 m, -2 m)
Suppose the river exerted a constant force of F* = (28 N)î – (14 N)ĵ on the fish as it moved
toward the hook.
b) How much work was done on the fish by the river?

B In the figure, block A has a mass of 9.06 kg. It rests on a smooth (assume frictionless) horizontal table and is connected by a very light horizontal string over an ideal pulley to block B, which has a mass of 2.80 kg. When block B is gently released from rest, how long does it take block B to travel 76.7 cm? Report your answer in seconds.
A force ofF1= 50.0 N is directed at an angle of 60° above the x-axis. A second force of F2 = 50.0 N is directed at an angle of 60.0° below the x-axis.= 50.0 N is directed at an angle of 60.0° below the x-axis. What is the vector sum of these two forces?
Two blocks are connected by a massless rope. The rope passes over an ideal (frictionless and massless) pulley such that one block with mass m1 = 13 kg is on a horizontal table and the other block with mass m2 = 7.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Use the coordinate system specified in the diagram. Under the same assumptions, write an expression for a2, the block of the mass m2 experiences in the y direction. Your answer should be in terms of the tension, T and m2 I have tried the following but they are incorrect: a2= (m2g-T)/m2 a2=g-(T/m2) a2=g-T/m2
A large truck is stuck off the main road in the mud. Two tow trucks have cables that are connected at the same point on the front of the stranded truck. The tow trucks are attempting to tow the vehicle in an easterly direction (consider this direction to be 0o). The 1st tow truck is exerting a force on the stranded truck that is represented by the vector F1=90i+6j. The 2nd tow truck is exerting a force represented by the vector F2=110i−10j. The forces are measured in pounds. 4a) Identify the vector F that represents the resultant force exerted on the vehicle at the point of attachment of the cables. Give your answer in the form F=ai+bj. 4b) Using the value of the direction angle, determine if the stranded truck will be pulled in a direction of due east (0o). If not, indicate if it will be pulled north of due east or south of due east. Round your answer to 2 decimal places.

The pulley is massless and frictionless and the cords joining the masses are ideal. The angle of the incline is 0=35°.
