the answer has to be answer C
Answer:
d
Explanation:
and just because trust me on this one my guy
15m/s is his running speed which is faster than the around 28mph limit for humans and he stops in 3 seconds with division he slows down at a rate of 5 meters per second which means he loses 5m/s velocity per second so 5meters per second per second
For the forces to be in equilibrium:
F 1 + F 2 + F 3 + F 4 = 0
i + j + i - j + 9 i + 2 j + F 4 = 0
11 i + 2 j + F 4 = 0
F 4 = - 11 i + 2 j
F 4 = ( -11, - 2 )
