A car moves along a straight road. It moves at a speed of 50 km/hr for 4 minutes, then
during the next 4 minutes it gradually speeds up to 100 km/hr, continues at this speed
for 4 minutes, then takes 4 minutes to gradually slow to a complete stop. Make a
sketch like the figures in Section 1.2 of your textbook, marking dots for the position
along the road every minute.
Which of the following choices best describes what can be determined exactly from Table 2.1 and Figure 2.1 for the entire 50-s interval?(a) The distance the car moved. (b) The displacement of the car. (c) Both (a) and (b). (d) Neither (a) nor (b).
George walks to a friend’s house. He walks 750 meters North, then realizes he walked too far. He turns around and walks 250 meters South. The entire walk takes him 13 seconds. What is his velocity in meters per second?
Also, is the acceleration due to gravity negative or positive or it depends?
I'm really confused. Please help and explain in an easy to understand.

- Please answer the following question(s): 1. The speed of a boat in still water is vá. A river flows with a speed of v₁. The boat travels distance of 19 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the vand v₁. Hint: Velocity=displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "v" and "v": Do v" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative. The resultant upstream velocity should be negative. vb vb Downstream positive Vr Upstream negative Vrarrow_forwardTask V:As a technical engineer in the army, you are part of a team in charge of testing and commissioning a new tankrecently purchased by the artillery.Field testing has revealed the following information:1) The tank moves from rest to a speed of 50 ??/ℎ? in 100 seconds.2) Using the breaking system, the tank is brought to a complete stop from a speed of 50 ??/ℎ? in 5 seconds.3) The maximum speed achievable by the tank is 90 km/hr.You are required to address all the questions below providing all calculations, graphs, and explanations asappropriate to back your answers.
