(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A car of a mass 1200Kg accelerate frm 2.5ms to 5.0ms while travelling up slope of 1 in 10 through a distance of 60m if the resistance to motion is 105N determine using both a energy method and d'alembert principle. any help would be much appreciated.

2. Relevant equations

Pe=mgh

ke=1/2mv²

inertia resistance (ma)

frictional resistance (Fr)

Gravitational force (mg sinΘ )

3. The attempt at a solution

600x6.25=3750

600x25=1500

1200x9.81x60sin3.71

11772x5.97=70274.19

ke=15000

pe-70274.10
