A woman walking her dog travels 200 m north, then 400 m west, then 500 m south. (a). What was the total distance she travelled? (b) What was the magnitude of her displacement for the entire trip?

SOLVE STEP BY STEP IN DIGITAL FORMAT 14. If the speed in (m/s) that a certain athlete reaches in a 200-meter race is described by the function v(x) =-0.005x(x - 300), where x is the recommended distance. a) What distance has the athlete traveled when he reaches his maximum speed?b) What is the maximum speed he reaches?

Please can you help me with questions 3 and 4?

scientific notation. If you are not sure about the number of significant figures, you can keep the number of figures as many as possible - You will not be punished for doing this.) QUESTION 3 An airplane needs to reach a forward velocity of 203.0 km/h (Please pay attention to the unit km/h here -- km = 1000 m, h = hour) to take off. On a 2000-m runway, what is the minimum uniform acceleration necessary for the plane to take flight if it starts from rest? OA 0.95 m/s2 O B. 0.87 m/s2 OC1.0m/s2 O D.0.79 m/s2 QUESTION 4 The motions ofa car and a truck along a straight road are represented by the velocity-time graphs in the figure.

Hi! Please answer this! Thank you so much:) 1. What is the displacement of a runner who joins a marathon if the race begins at a certain park, runs 42km, and finishes the race at the same location in the said park? Explain briefly. 2. One afternoon, a couple walks three-fourths of the wayaround a circular lake, the radius of which is 1.5 km.They start at the west side of the lake and head duesouth to begin with. (a) What is the distance theytraveled? (Cutnell and Johnson, 2012) (b) describe thecouple’s displacement as compared to the distancetraveled.
