A car is moving along a straight road while speeding up d A hockey puck slides along a smooth ( e A hockey puck slides along a rough concrete surface f A cockroach is speeding up from rest g A rock is thrown horizontaily, air resistance is negligible h. A rock is thrown horizontally, air resistance is substantial i A rock is dropped vertically, air resistance is rstand the meaning and the basic ap ations of Newton's 1st oblem, you are given a diagram (Figure 1 )representing the f an object a motion diagram The dots represent the objects at moments separated by equal intervals of time. The dots are d by arrows representing the object's average velocity during sponding time interval A rock is dropped vertically, air resistance is substantial is to use this motion diagram to rce acting on the object You will then determine which force and which situations may correspond to such a motion the direction of Part D Which of these situations describe the motion shown in the motion diagram at point A? Type the letters corresponding to all the right answers. Do not use commas. For instance ad 1 of 1 Previous Answers Completed Part E Which of these situations describe the motion shown in the motion diagram at point B? Type the letters corresponding to all the right answers. Do not use commas. For instar

Explanation / Answer
