Question

Please help! I especially need help with the second question but help with the first one would be most appreciated!

Answer 1

a) Team A will win.

b) The losing team will accelerate towards the middle line with 0.01 m/
`s^(2)`

Step-by-step explanation:

Given that Team-A pulls with a force ,
`F_(1) = 50N`

and Team-B pulls with a force ,
`F_(1) = 45N`

∵
`F_(1) > F_(2)`

The rope will move in the direction of force
`F_(1)`.

∴ Team-A will win.

b) Considering both the teams as one system of total mass ,
`m = 246+253 = 499 kg`

Net force on the system ,
`F = F_(1) - F_(2)` = 50-45 = 5N

Applying Newtons first law to the system ,

F = ma , where 'a' is the acceleration of the system.

Since , both the teams are connected by the same rope , their acceleration would be the same.

∴ 5 = 499×a

∴ a = 0.01 m/
`s^(2)`
