If his speed is 37.1 m/s when he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance.An ordinary light bulb consumes 40 W of power. Through what height could a 1000-N object be lifted expending the same amount of power for 6 hours? Group of answer choices: 360 m 860 m 720 m 650 m 430 m

Assuming other losses are negligible, determine the magnitude of the total resistive force FR acting on the car (due to friction, air resistance, etc.). Use this conversion as needed: 1 hp = 746 W. FR = × 10³ NA roller coaster starts with a speed of 4.1 m/s at a point 51 m above the bottom of a dip.
