1. A 12 kg barrel is pulled up by a rope. The barrel accelerates at 1.2 m/s2. Find the force exerted by the rope. Show all your work.

Respuesta :

F-mg=ma
F-(12kg)(9.8m/s^2)=(12kg)(1.2m/s^2)
F-117.6N=14.4N
F=132 Newtons

The force will be "14.4 N".

The given values are:

Mass,

m = 12 kg

Acceleration,

a = 1.2 m/s²

As we know the formula,

→ [tex]Force = Mass\times acceleration[/tex]

By substituting the values, we get

→           [tex]=12\times 1.2[/tex]

→           [tex]= 14.4 \ N[/tex]

Thus the above answer is correct.
