Question

plusminus The Graph of a Sports Car's Velocity The graph in the figure shows the velocity v of a sports car as a function of time t. Use the graph to answer the following questions. Find the maximum velocity V_max the car during the ten-second interval depicted in the graph. Express your answer in motors per second to the nearest integer. During which time interval is the acceleration positive? Indicate the best answer. t = 0 lessthanorequalto to t = 6s t = 0 lessthanorequalto to t = 4s t = 0 lessthanorequalto to t = 10s t = 4 lessthanorequalto to t = 10s t = 2 lessthanorequalto to t = 6s This question wit be shown after you complete previous question (s). This question will be shown after you complete previous question (s). Find the distance d_o 2 traveled by the car between t = 0 s and t = 2 s. Express your answer In meters to the nearest integer

Explanation / Answer

from the graph

the velocity increases from t = 0 t0 t = 4s and at t = 4 s the velocity is maximum

part A

each division ov velocity scale = 10 m/s

vmax = 50 + 10/2 = 55 m/s   <<<----------answer

part B

from t = 0s to t = 4 s <<<----------answer
