Question

A chute delivering shipments of freight is so designed that the boxes starting from rest, receive a uniform acceleration of 18 ft. / sec² on the first section which is 18 ft. long. Then they are retarded by a 6 ft. / sec² uniform deceleration on the next section. It the total time consumed in shooting both sections of 12 sec.

Determine

(1) the time at the first and second sections in sec.

(2) the velocity after the time at the first section, in ft. / sec.

(3) the distance or displacement of the second section. in ft.

(4) the velocity in ft. / sec. at the end of second section.
