A150kg motorcycle starts from rest and accelerates at a constant rate along a distance of 350m. the applied force is 250n and the coefficient of kinetic friction is 0.03.
a - find the net force applied to the motorcycle.
b - find the acceleration of the motorcycle.
c - what is its speed at the end of 350m?
d - find the elapsed time of this acceleration.
[explain and show work]
answer : alternating current
explanation : alternating current will produced by a wire breaking magnetic field lines and changing the polarity.
because according to faraday's law when the magnetic field interact with the electric circuit then produce an emf that means induced a current in a circuit. and when polarity will change then direction of current will reverse.
so, this current called alternating current.
he walks 33° north of east for 80 m starting from the center. the drawing is made according to the statement.
momentum = (mass) x (speed) .
so 907,175 kg-m/s = (36,287 kg) x (speed)
divide each side by (36,287 kg):
speed = (907,175 kg-m/s) / (36,287 kg)
speed = 25 m/s
that's the truck's speed. we can't do anything that involves the truck's velocity, because we don't know what direction the truck is moving.
i would think form in reponse to tensional forces
