  • u = 20 m/s
  • v = 30 m/s
  • t = 10 s

➡ 30 = 20 + a × 10

1. As you get ready for bed, you roll up one of your socks into a tight ball and toss it into the laundry
yKpoI14uk [10]

Answer:

When you toss a rolled up sock across the room, it travels faster as it becomes round and has more weight added on it and this causes the sock to travel in the direction you wish and this gives you a high chance of the sock going straight into the laundry basket, no matter how far away you are.

On the other hand, throwing a sock without rolling it up will cause the sock to just flat down as you throw it. It will travel at a low speed because it has no weight on it since it is flat, and if you try to throw it, it will atleast land 21 cm away from you. About a 0% chance of it getting in the basket.

Hope this helped! =>
