Try to masterize this chapter today.

hail, warriors of the chat-hall! i, stride in when the feast is cold, too late to plunder the words. fate marked my delay! forgive my months-long vanishing. ⚔️🍻

wait, sine when telegram ai became this advanced? anyways, since the intensive study programme is ongoing and it's getting late, let's end the day with chap 2💃💃

these are noob-level questions, but they're great for winding down at night.😂😂

i hope i'll send the answers by tomorrow😭 i'm so forgetful these days... g-bye!!

here's the answer for the spinning top question

so what's the actual working ?
First, the question mentioned the ball decelerates, meaning the resultant force is acting upwards. The ball has its weight acting downwards. The overall equation is as below:
F_{net} = ma
F_{sand} - Weight = ma
F_{sand} = mg + ma
F_{sand} = 4.50 (9.81 + 8 x 10^2)
F_{sand} = 3644 N ~ 3640 N

how about this question then? Almost half of the people chose B.
