Description

This program simulates loading a small mass on a slope. The mass initially slides on the slope surface at an initial speed of 30 m / s. The ball on the slope is projected vertically at 30 m / s after 1 second of sliding. The spring bevel pops up. Assuming that the internal force of the system does not change when the ball is ejected, it will not affect the system. Will the ball return to the block after it pops up? If the angle of the slope is set to zero, will it help thinking?

Display:

Green arrow: Velocity of the ball along the slope (Vsb meters / second) and the speed of the vertical slope (Vnb meters / second)

Red arrow: the speed of the pulley along the slope (Vsa meters / second)

Green dots: the track of the ball every second interval

Black dots: the track of the pulley every second interval

Adjustable parameters:

c: slope elevation (degrees)

Simulation operation:

Select the angle c value (degrees) of the inclined plane and press Play to perform the simulation. After the simulation is completed, press Reset to reselect the simulation conditions for the next simulation.

Button: Show track: If you want to show the track of the pulley and the ball every one second, press this button after setting the parameter c. The track of the two objects will be displayed when you press Play to perform the simulation. If you press Play, press this Button, the simulation screen only displays the trace after pressing the button.

Display bar parameters:

t: time (seconds)

Sa: the displacement of the mass in the direction of the slope (meters)

Vsa: the speed of the mass in the direction of the slope (m / s)

Vsb: speed of the mass in the direction of the slope (m / s)

Vnb: speed of the mass in the direction of the perpendcular to the slope (meters / second)
