Homework Statement
The acceleration of a particle is defined by the relation a=0.4(1-kV), where k is a constant. Knowing t=0 the particle starts from rest at x=4m and that when t=15s, V=4 m/s, determine...
a)the constant k
b)the postion when V=6m/s
c) the maximum velocity of the particle
Homework Equations
The Attempt at a Solution
a=0.4(1-kV)
0.4(1-kV)=dV/dt...im lost after this, can someone just simply point me in the right direction.
