Aperson in a kayak starts paddling, and it accelerates from 0 to 0.680 m/s in a distance of 0.428 m. if the combined mass of the person and the kayak is 82.7 kg, what is the magnitude of the net force acting on the kayak?

Net force, F = 44.66 N

Explanation:

It is given by,

Initial velocity of the person, u = 0

Final velocity of the person, v = 0.68 m/s

Distance, s = 0.428 m

Combined mass of the person and the kayak, m = 82.7 kg

We need to find the net force acting on the kayak i.e.

F = ma...........(1)

Firstly, we will calculate the value of "a" from third equation of motion as :

Put the value of a in equation (1) as :

F = 44.66 N

So, the net force acting on the kayak is 44.66 N. Hence, this is the required solution.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
