Chapter D - Problems Blinn College - Physics 2425 - Terry Honan Problem D.1 The same force acts at different times on two masses. m 1 is given an acceleration of 4 m ë s 2 and m 2 is given an acceleration of 1 m ë s 2 . (a) What is the ratio of the masses, m 2 ê m 1 ? (b) Suppose the two masses are combined and the same force is acted on the combination. What is its acceleration? Problem D.2 A 2 ton truck provides an acceleration of 3 ft ë s 2 to a 4 ton trailer. If the truck exerts the same force on the road while pulling a 16 ton trailer, what acceleration results? Assume there are no resistive forces. Problem D.3 A 5 g bullet is accelerated to 300 m ê s down a 72 cm gun barrel. Assuming a uniform acceleration, what is the net force on the bullet in the gun barrel? Problem D.4 The displacement of 20 kg mass as a function of time in SI units is given by: r H t L = Y 2 t 3 - 9 t - 15, - 6 t 2 + 5 t + 18 ] . What is the net force acting on the mass as a function of time? What is the net force at
