Step-by-step explanation:
Answer:
A) C = 211
B) C = 15.05
Step-by-step explanation:
To get your answer you need to subtract the final answer with the number in the equation. So... 458 - 247 = 211. Hence C is 211
First:
F=m.a
=4*7
=28N
Second:
F=m.a
28=m.2. (force is constant,so F=28N)
28/2=m
m=14kg.
