A farm truck travels due east with a constant speed of 9.50 m/s along a horizontal road. A boy riding in the back of the truck tosses a can of soda upward (Fig. P3.40) and catches it at the same loca- tion in the truck bed, but 16.0 m farther down the road. Ignore any effects of air resis- tance. (a) At what angle to the vertical does the boy throw the can, relative to the moving truck? (b) What is the can’s ini- tial speed relative to the truck? (c) What is the shape of the can’s trajectory as seen by the boy? (d) What is the shape of the can’s trajectory as seen by a stationary observer on the ground? (e) What is the initial velocity of the can, relative to the stationary observer?

When a lead acid car battery is recharged by the alternator, it acts essentially as an electrolytic cell in which solid lead(ii) sulfate is reduced to lead at the cathode and oxidized to solid lead(ii) oxide at the anode. suppose a current of is fed into a car battery for seconds. calculate the mass of lead deposited on the cathode of the battery.
