Having aced her physics class, a student gets a co having aced her physics class, a student gets a cool summer job with nasa that involves playing golf on distant planets. for the first drive on the 4th hole on the planet lgis, the total velocity of her ball is as plotted to the left. the ball lands at the same vertical level at which it starts. along with being distant, the planet lgis is airless, so we can ignore air resistance.
1) how far will her ball go horizontally before it strikes the ground on the first bounce?
2) what is the acceleration due to gravity on lgis?
3) what is the maximum height the ball reaches above the surface?

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
