Aperson in a kayak starts paddling, and it accelerates from 0 to 0.61 m/s in a distance of 0.39 m. if the combined mass of the person and the kayak is 74 kg, what is the magnitude of the net force acting on the kayak?

35.3 N

Explanation:

U = 0, V = 0.61 m/s, s = 0.39 m

Let a be the acceleration.

Use third equation of motion

V^2 = u^2 + 2 as

0.61 × 0.61 = 0 + 2 × a × 0.39

a = 0.477 m/s^2

Force = mass × acceleration

F = 74 × 0.477 = 35.3 N

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
