I need steps to solve this to understand it

You measure the motion of a dynamics cart using a motion sensor.  You then plot the cart’s position vs. time and velocity vs. time.  The best way of finding the average acceleration of the cart is to find: a. the y-intercept of the position vs. time plot. b. the y-intercept of the velocity vs. time plot. c. the slope of the position vs. time plot d. the slope of the velocity vs. time plot. e. none of the above

The topic is kinematics. I need the answers with complete solution and explanation. Thank you!

What is the acceleration (in units of feet per second squared) of a car that goes from 16 mph to 75 mph in a 10.0 second time period? How far does the car travel during that acceleration in units of feet? Make a list of all given values, units, and the variables they represent. Write the general form of the equation you are going to use. Solve the equation.

Solutions: a. v after is use: V₁ = V₁ - gt vy=20 m/s-(9.8 m/s²)(1.0s) vf= 20 m/s -9.8 m/s vf = 10.2 m/s b. v after 2s use: c. d after 1s use: v₁ = v₁ - gt vy=20 m/s-(9.8 m/s²)(2.0s) vf= 20 m/s - 19.6 m/s vf = 0.4 m/s d = v₁t - 912 2 d=20m/s(1.0s) - (9.8 m/s²)(1.0s)² 2 d=20m-4.9 m d=15.1 m (positive sign denotes that the object is moving upward) d. t from origin to maximum height Note: An object thrown upward will reach a certain point (maximum height) where it will momentarily stop and then start to move downward. At this point, vy= 0. V₁ = V₁ - gt Use: Manipulating the equation, V₁ - Vf 9 t = t=20 m/s-0 9.8 m/s² t = 2.04 s e. d from origin to maximum height use: d = v₁t d=20m/s (2.04 s) - (9.8 m/s²)(2.04s)² - gt² 2 2 d = 40.8 m -20.40 m d = 20.4 m
