A picture of two children pulling on a stuffed animal in opposite directions. A free body diagram with 2 force vectors. The first vector is pointing right, labeled F Subscript p 2 Baseline = blank N. The second vector is pointing left, labeled F Subscript p 1 Baseline = 3.5 N. The left vector is longer than the right. A girl and boy pull in opposite directions on a stuffed animal. The girl exerts a force of 3.5 N. The mass of the stuffed animal is 0.2 kg, and it is accelerating to the right 2.5 m/s2.What is the force that the boy is exerting?N

Learning goal: to understand newton's 1st law. newton's principia states this first law of motion: an object subject to no net force maintains its state of motion, either at rest or at constant speed in a right line. this law may be restated as follows: if the sum of all forces acting on an object is zero, then the acceleration of that object is zero. mathematically this is just a special case of the 2nd law of motion, f⃗ =ma⃗ , when f⃗ =0. when studying newtonian mechanics, it is best to remember the 1st law in two ways: if the net force (i.e., sum of all forces) acting on an object is zero, the object will keep moving with constant velocity (which may be zero). if an object is moving with constant velocity, that is, with zero acceleration, then the net force acting on that object must be zero. complete the following sentences to see if you can apply these ideas. part a if a car is moving to the left with constant velocity, one can conclude that

Many science fiction movies and tv shows have detected using a nuclear weapon to destroy astroids what problems does plait see with this plan

What is reflection, what is refraction, and what is diffraction. what some similarities or differences between the three.
