Answer:
Mass is 5kg
Step-by-step explanation:
Calculate the mass of an object if a force of 20 N produces an acceleration of 4 m/s2.
from newton's second law of motion , which states that
the rate change in momentum of an object is directly proportional to the force applied
definition of terms you should know.
a force is tat which tends to cane a body state of rest or uniform motion in a strait line
mass is the quantity of matter in a body
acceleration is change in velocity per time
therefore,
f∝m(V-U)/t
f=km(V-U)/t
k=1
f=m(V-U)/t
(V-U)/t=a
f=ma
f= 20 N
a=4 m/s2.
20=m*4
m=5kg
