Explanation:
Answer:
C. 640
Explanation:
The minimum force would occur in a frictionless environment and act parallel to any abutting surface.
F = ma = 160(4) = 640 N
Answer:
20N
Explanation:
The force (Hooke's Law) is proportional to the deformation. To extend the spring 4 times longer, you will need 4 times the force. In total, 20 N
Due to the principle of conservation of energy, the work done by the engine to move the scooter converts into kinetic energy of the scooter:

where M is the combined mass of scooter and rider, and v is the velocity of the scooter. Therefore, we can find the velocity as:
