OBJECT A HAS INITIAL VELOCITY 18 MPH, AND OBJECT B HAS INITIAL
VELOCITY6MPH. IF A'S ACCELERATION IS0.06 MPH/S AND B'S IS 0.10 MPH/S,
HOW LONG MUST THEY ACCELERATE BEFORE THEY HAVE THE SAME VELOCITY

Hello jayrock, this is an application of the motion equation:

V(final) = V(initial) + At

We know that the two final velocities are equal so:

Va(initial) + A(a)t = Vb(initial) + A(b)t

Solving for t:

t = Va-Vb / Ab-Aa

t = (18-6) MPH / (0.10-0.06) MPH/sec

t = 300 sec

Redhoss
