F=ma so 160N=20kg*8m/s
160 N is the answer
Answer:
Step-by-step explanation:
Answer:
39 units²
Step-by-step explanation:
A line segment from R to V will divide the figure into a 5 by 6 rectangle and a triangle with base 6 and height 3. Appropriate area formulas will help you find the areas of these parts. The total area is the area of the parts.
rectangle area = L·W = 5·6 = 30 . . . units²
triangle area = 1/2·b·h = 1/2·6·3 = 9 . . . units²
Then the polygon area is ...
polygon area = rectangle area + triangle area = (30 +9) units² = 39 units²
