Answer :
143 Newton force is the magnitude of the force applied.
force is mass × acceleration
acceleration= change in velocity / time
(20-10 )/ 7sec
10/7 m/s^2
force =100* 10/7
100/7 N
142.857 N
143 N
Newton is the abbreviation for the SI unit of absolute force known as newton (N). . The force necessary to accelerate one kilogram of mass one meter per second is what is meant by this .In the foot-pound-second system, one newton is equivalent to around 0.2248 pounds of force in another word, 100,000 dyne in centimeter-gram-second (CGS) system. The newton was given its name in honor of Sir Isaac Newton, whose second rule of motion outlines the modifications that a force may cause in a body's motion.
