On a sunny day, a family decided to take sail on a nearby lake. During sailing the wind applies a force of 25N north on the sails of the sailboat. The
water however exerts a force of 20 N east. If the total mass of both the sailboat and the crew (family on board) is 20kg, what is the magnutude and
direction of the acceleration produced?

The acceleration of the boat is obtained as 1.6 ms-2.

We have to obtain the resultant force acting on the boat in order to obtain the acceleration of the boat.

Resultant force on the boat = √(25)^2 + (20)^2 = √625 + 400 = 32 N

Now recall that from Newton's laws; F = ma

m= mass of the body

a = acceleration of the body

32 N = 20Kg × a  

a =  32 N/20Kg

a = 1.6 ms-2
