Question

A particle moving along a straight line is subjected to a deceleration a=-2v^3 m/s2.
If it has a velocity v=8 m/s and a position x=10 m when t=0, determine its velocity and position when t=4s.

I tried to integrate the deceleration equation, but it didn't work.

Answer 3

A particle moving along a straight line is subjected to a deceleration a=(-2v^3) m/s^2, where v is in m/s. If it has a velocity v=8 m/s and a position s=10m when t=0, determine its velocity and position when t=4s
