Compression in a connecting rod during braking: check 1
Difficulty: ★★☆Info
Maths4U Original · Short practice
Two carts move right at \(\displaystyle \frac{12m}{s}\) on a horizontal track, joined by a light rigid horizontal rod. The front cart has mass 6 kg and the rear cart 6 kg. A brake on the front cart exerts 42 N left. The rear cart has constant resistance 6 N left; there is no other horizontal resistance. The rod remains attached until the first stop.
Find the positive deceleration magnitude in \(\displaystyle \frac{m}{s^{2}}\).
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.
