A constant force F, pulls a 50kg block at a constant speed over a rough horizontal surface, AB, as shown in the diagram. The coefficient kinectic friction between the block and the surface is 0.4. Calculate the magnitude of the:
1.) Force, F
2.)Normal force
3.)Frictional force​

Electoral current force mechanical advantage if the wheel and axle is 2 n and the output force is 20 n

Are there options for this?

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.

It would stay the same
