a person in a kayak starts paddling, and it accelerates from 0 to 0.36 m/sec in a distance of 0.8m if the combined mass of the person and the kayak is 80 kg,what is the magnitude of net force acting on the kayak...??

The School Subject is the subject you are studying, not the name of your school.

at = .36

1/2 at^2 = 0.8

a = 0.081

Now you know that F = ma, so you can find F.

To find the magnitude of the net force acting on the kayak, we can use Newton's second law of motion:

F = m * a

where F is the net force, m is the combined mass of the person and the kayak, and a is the acceleration.

Given:
m = 80 kg (combined mass)
a = 0.36 m/sec^2 (acceleration)

Substitute the given values into the formula to find the magnitude of the net force:

F = 80 kg * 0.36 m/sec^2
F = 28.8 N

Therefore, the magnitude of the net force acting on the kayak is 28.8 Newtons.
