A car starts from xi = 12 m at ti = 0 and moves with the velocity graph shown in figure below.
Part A
What is the object's position at t = 2 s?
Part B
What is the object's position at t = 3 s?
Part C
What is the object's position at t = 4 s?
part A )
X(t= 2sec) = 12m +(2*4 +8*.5*2)
X(t=2sec) = 12+16
X(t=2sec) = 28 m
Part B)
X(t=3sec) = 12+(0.5*3*12)
X(t=3sec) = 30m
Part C )
X (t=4) = 12+(0.5*3*12 -0.5*1*4)
X(t=4sec) = 28m
I know that t=2 is 36 m. This is because if you find the area of the triangle under t=2, you get an area of 8. There is alos a remaining rectangle that also has a area of 8. together you get 16, plus the starting 20 m.
Solve t=3 the same way. Not sure about t=4 yet, but the car changes directions at t=3, at 0m/s.
A car starts from xi = 12 m at ti = 0 and moves with the velocity graph shown in figure below.

A particle starts from the origin at t = 0 and moves along the positive x axis. A graph of the velocity of the particle as a function of the time is shown in the figure; the v-axis scale is set by vs = 6.0 m/s. (a) what is the coordinate of the particle at t = 5.0 s? (b) what is the velocity of the particle at t = 5.0 s? (c) what is the acceleration of the particle...
