A boat moves through the water with two forces acting on it. One is a 2.51×103 N forward push by the motor, and the other is a 1.88×103 N resistive force due to the water. What is the acceleration of the 1384.1 kg boat? Answer in units of m/s 2

Respuesta :

Answer:

Acceleration [tex]a=0.455m/sec^2[/tex]

Explanation:

We have given that the force by the motor [tex]F=2.51\times 10^3N=2510N[/tex]

Resistive force by the water [tex]F=1.88\times 10^3N=1880N[/tex]

So net force [tex]F_{NET}=2510-1880=630N[/tex]

Mass of the boat = 1384.1 kg

According to newton's second law F=Ma, here M is mass and a is acceleration

So [tex]630=1384.1\times a[/tex]

[tex]a=0.455m/sec^2[/tex]
