4. Force-versus-Time Curve. The magnitude of the net force exerted in the x direction on a 2.50-kg particle varies with time as shown in the force-time curve. Find: (a) the impulse of the force over the 5.00-s time interval; (b) the final velocity the particle attains if its originally at rest; (c) its final velocity if its original velocity is -2.00i m/s; and (d) the average force exerted on the particle for the time interval between 0 and 5.00 s.

Problem: If the diameter of a bicycle wheel is 622 mm, what is the diameter of the wheel in inches? (1 inch = 25.4 mm) Solution: 622 mm x 1 inch/25.4 mm = 24.5 inches. Make sure to show all the units in your solutions, as seen in the example above.
10.(0-2) Dry ice is solidified carbon(IV) oxide. It is an ingredient in so-called cooling mixtures. It is obtained by expanding liquid carbon(IV) oxide and pressing. Under normal conditions, dry ice sublimates easily. Its density is about 1.4-9,. Calculate the volume under normal conditions of cm the carbon(IV) oxide that results from the complete sublimation of 5 cm3 of dry ice.
