2. 1D Motion / Kinematics / Velocity-Time Graphs & Acceleration / Problem 12

The velocity versus time data of a remote control car collected during a high school experiment is shown in the figure below. The car moves along a straight line. Initially, at t=0 s the car was located at x₀= 1.0 m. Find the position, velocity, and acceleration of the car at t = 40 s.

A

x (40s) = 120 m
v_x (40 s) = 3 m/s
a_x (40 s) = 0 m/s²

B

x (40s) = 121 m
v_x (40 s) = 4 m/s
a_x (40 s) = 0.05 m/s²

C

x (40s) = 130 m
v_x (40 s) = 3 m/s
a_x (40 s) = 0 m/s²

D

x (40s) = 131 m
v_x (40 s) = 4 m/s
a_x(40 s) = 0.05 m/s²
