Newton’s third law: identifying the two bodies: check 1
Difficulty: ★★☆Info
Maths4U Original · Short practice
During an interaction A exerts a horizontal force 17 N right on B. Separately, a block of mass 4 kg rests on a horizontal support with no other vertical applied force. Use \(\displaystyle g= \frac{10m}{s^{2}}\). All horizontal signs below use right as positive.
Find the horizontal force on B from A, positive right, in N.
Enter one exact number or fraction unless the question specifies rounding. Use the requested units and positive direction; enter the number without its unit. Angles here use degrees. Give full reasoning separately for written problems.
