Problem 10: A car starts at rest and moves along a perfectly straight highway with an acceleration of a₁ = 10 m/s² for a certain amount of time t₁. It then moves with constant speed (zero acceleration) for next t₂ seconds and finally decelerates with an acceleration a₂ = -10 m/s² for next time t3 seconds until it comes to a complete stop. The total time of motion is t₁ + t₂ + t3: = 25 s. The total distance travelled by the car is 1 km. Find t₂.

Please answer 3, 4, 5, 6, 8, 9, 10, 12 1 is 0, 2 is 0, 7 is point A, 11 is 2.  I included a picture of someone who solved but they were mostly incorrect. Please do not answer if the solution set I provided with the incorrect answers was you. I appreciate the attempt, but the solutions for 3, 4, 5, 6, 8, 9, 10, 12 were marked wrong, so unless you have different answers, please do not submit the same incorrect solution set. The wheel is attached to the spring. The mass of the wheel is m=20 kg. The radius of the wheel is 0.6m. The radius of gyration kG=0.4 m. The spring’s unstretched length is L0=1.0 m. The stiffness coefficient of the spring is k=2.0 N/m. The wheel is released from rest at the state 1 when the angle between the spring and the vertical direction is θ=30°. The wheel rolls without slipping and passes the position at the state 2 when the angle is θ=0°. The spring’s length at the state 2 is L2=4 m. (1) If the mass center G is set as the origin (datum), the gravitational…

I need these three parts answered (Multiple Choice). If you can not answer all three parts please leave it for another tutor to answer.
