A power-shift crawler tractor is excavating tough clay and pushing it a distance of 95 feet. Maximum reverse speeds are as follows: first range, 3 mph; second range, 5 mph; and third range, 8 mph. Rated blade capacity is 10 LCY. Estimate dozer production if the job efficiency factor is 0.83.Use Tables 1and 2.

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
