Answer:
F = 12000 N = 12 KN
Explanation:
First we need to find the acceleration of the bad boys by using second equation of motion:
s = Vi t + (1/2)at²
where,
s = distance covered = 5 m
Vi = Initial Velocity = 0 m/s
t = time taken = 0.5 s
a = acceleration = ?
Therefore,
5 m = (0 m/s)(0.5 s) + (1/2)a(0.5 s)²
a = 2(5 m)/(0.5 s)²
a = 40 m/s²
Now, we calculate the force applied by Newton's Second Law:
F = ma
where,
F = force = ?
m = mass of bad guys = 300 kg
Therefore,
F = (300 kg)(40 m/s²)
F = 12000 N = 12 KN
