Answer:
F=m[vf-vi]/t
t=m[vf-vi]/F
t=[1200][2]/[550]
t=4.36s
Explanation:
A tow truck will take 4.36 s.
Given:
Force, F= 550N
Mass, m= 1200kg
Final Velocity vf= 2 m/s
Initial Velocity vi= 0 m/s
A force can cause an object with mass to change its velocity (e.g. moving from a state of rest), i.e., to accelerate.
[tex]F= m*a[/tex]...............(i)
and [tex]a=\frac{[v_f-v_i]}{t}[/tex]...............(ii)
So, on substituting (ii) in (i)
[tex]F=\frac{m[v_f-v_i]}{t} \\\\t= \frac{m[v_f-v_i]}{F}\\\\t= \frac{[1200][2-0]}{[550]} \\\\t=4.36s[/tex]
Thus, time taken is 4.36 s.
