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]

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

i will answer your question if you answer mine

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
