SUPER URGENT ! Power question
A truck of mass m is accelerated from rest at t=0 with constant power P along a level road
show that the position of the truck is related to its speed by x=(m/3P)v^3
the position of the truck is previously found as:
x=(8P/9m)1/2*t3/2
I also found the v=(2P/m)1/2*t1/2
Integral
I have not found anyway to do this problem yet. I tried to to relate v to x by taking the integral of v by integrate (m/3P)v^3 but I am stuck.
