If he were to try to jump without giving that downward push, there would be no opposite push from the ground, and two things would happen: (1) shaun would not get very high off the ground, and (2) shaun’s board would not stay pressed against his feet, having no upward force applied to it. the passage above reflects the principles of a. newton’s first law of motion c. newton’s second law of motion b. newton’s third law of motion d. all of the above

The position of a dragonfly that is flying parallel to the ground is given as a function of time by r⃗ =[2.90m+(0.0900m/s2)t2]i^− (0.0150m/s3)t3j^. a: at what value of t does the velocity vector of the insect make an angle of 34.0 degree clockwise from the x-axis? b: at the time calculated in part (a), what is the magnitude of the acceleration vector of the insect? c : at the time calculated in part (a), what is the direction of the acceleration vector of the insect?
