Question

The vehicle with parameters given in Exercise 2.2 accelerates from to 60 mi/h in 13.0 s for the two following acceleration types: (1) constant FTR and (ii) uniform acceleration.
(a) Plot on the same graph the velocity profile of each acceleration type
(b) Calculate and compare the tractive energy required for the two types of acceleration. FTR =const. = 1548 N​

Answer 1

Answer:

Horizontal projectile motion equations

As a result, we have only one component of initial velocity - Vx = V, whereas Vy = 0. Horizontal distance can be expressed as x = V * t . Vertical distance from the ground is described by the formula y = – g * t² / 2 , where g is the gravity acceleration and h is an elevation.
