A person wants to slide the 100−lb box across the floor by pushing on it with the force P located as shown. The coefficients of static and kinetic friction between the box and the floor are 0.20. a) Is it possible to slide the box with an acceleration of 8.00 ft/s2 to the right without tipping the box? Support your answer with a calculation. b) If so, calculate the value of P that gives this acceleration.
