Answer:
3000 N
Explanation:
We have,
• Mass, m = 1000 kg
• Acceleration, a = 3 m/s²
We have to find force required, F.
F = ma
F = 1000 × 3 N
F = 3000 N (Answer)

Answer:
A+B+C=7j+k
Explanation:
A=3i+4j
B=2i-2j+4k
C=i+5j-3k
A=3i+4j
+
B=<u>2</u><u>i</u><u>-</u><u>2</u><u>j</u><u>+</u><u>4</u><u>k</u>
i+2j+4k
A+B=i+2j+4k
+
C=<u>-i+</u><u>5</u><u>j</u><u>-</u><u>3</u><u>k</u>
7j+k
A+B+C=7j+k
