A truck is moving at 35m/sec. How fast will the police have to accelerate to catch the truck in 1 min
assuming that the police car starts from rest as soon as the truck passes it ...
$\displaystyle vt = \frac{1}{2}at^2$
where $\displaystyle v$ = truck's constant speed
$\displaystyle t$ = time in seconds to catch the truck
$\displaystyle a$ = acceleration of the police car in m/s^2
