Question

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

Answer 1

Answer:

Acceleration $a=0.455m/sec^2$

Explanation:

We have given that the force by the motor $F=2.51\times 10^3N=2510N$

Resistive force by the water $F=1.88\times 10^3N=1880N$

So net force $F_{NET}=2510-1880=630N$

Mass of the boat = 1384.1 kg

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

So $630=1384.1\times a$

$a=0.455m/sec^2$
