A boat of mass 350kg starts off from rest and travels a distance of 60m in 10s at constant acceleration, find the net force acting on the boat.

Answer 1

We can use the equation:

distance = (initial velocity)(time) + (1/2)(acceleration)(time)^2

Rearranging and plugging in the given values, we get:

(1/2)(acceleration)(time)^2 = distance - (initial velocity)(time)
(1/2)(acceleration)(10s)^2 = 60m - 0m/s * 10s
acceleration = 1.2 m/s^2

Now, we can use Newton's second law:

net force = mass x acceleration
net force = 350kg x 1.2 m/s^2
net force = 420 N

Therefore, the net force acting on the boat is 420 N.
