Answer:
.team 1 a = 20.8 m/s² team 2 a = 19.2 m/s²
Explanation:
Let's use Newton's second law to calculate the acceleration of the two groups
F = ma
a = F / M
Group 1
a = 9 1354/9 65
a = 20.8 m / s²
Group 2
a = 9 1364/9 71
a = 19.2 m / s²
If the two groups pull against each other, group 1 should win, by creating a greater acceleration.
Δa = 20.8 -19.2
Δa = 1.6 m / s²
