Answer the following questions: The changes in the velocity of a car in specific time intervals are given in the following table. Explain For all uniformly accelerated motions, the velocity-time graph is a straight line.

Answer the following questions: The changes in the velocity of a car in specific time intervals are given in the following table. The velocty-time graph in figure shows that, For nonuniformly accelerated motions, the velocity-time graph may have any shape depending on how the acceleration changes with time.Explain.

Answer the following questions: The changes in the velocity of a car in specific time intervals are given in the following table.The velocty-time graph in figure shows that, The velocity changes by equal amounts in equal time intervals. Thus, this is uniformly accelerated motion. How much does the velocity change in every 5 seconds? Find the distance covered by the car in the time interval 10 seconds to 20 seconds.
