A person is driving their motorized wheelchair up a 5-meter ramp that is inclined at an angle of 5° above the horizontal. The combined mass of the person and wheelchair is 117 kg. What is the force exerted by the motor?

A. 58 N
B. 580 N
C. 1,159 N
D. 11,590 N

Answer :

The correct answer is 580 N (option b). It is the upward force needed to support the wheelchair and its load when driving up a ramp inclined at 5° above the horizontal. therefore the correct option is b) 580 N

The upward force to support the wheelchair and its load can be calculated using the components of the forces involved. Given that the combined mass is 117 kg, and the ramp is inclined at 5° above the horizontal, the correct answer is 580 N (option b).
