Can you kindly show the equation that you used for each part please

1. The following velocity vs time graph shows the motion of a car along a straight, level road. (a) By writing down appropriate kinematics equations and substitution of values, determine the net displacement of the car for the entire motion. [6] (b) By stating the definition, determine the average velocity of the car during 0 to 50 s. [2] (c) By stating the definition, determine the average velocity of the car during 0 to 20 s. [2] 2. Starting from rest a car travels with constant acceleration of 3.5 mfs 2 to attain a speed of 18.0 mfs. The car then continues to travel in the same direction at a constant deceleration for 10 s before coming to stop. [8] By drawing a diagram of the entire motion of the car, showing coordinate axis and applying kinematics equations I. Determine the distance travelled by the car from rest to attain speed of 18.0 mfs. II. Determine the net displacement of the car during the entire motion
