14. A force is applied to a 100-kg go-cart to accelerate
it from 10.0 m/s to 20.0 m/s over a 7.00 s time frame.
If the acceleration is assumed to be constant over the
time frame, what is the magnitude of the force
applied?


A. 50.0 N
B.123 N
C.143 N
D.150 N



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.
