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

Acceleration
`a=0.455m/sec^2`

Step-by-step explanation:

We have given that the force by the motor
`F=2.51* 10^3N=2510N`

Resistive force by the water
`F=1.88* 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* a`

`a=0.455m/sec^2`
