Calculating Final Velocity on a Ramp

[QUOTE="Khaled Abdullatif, post: 5995844, member: 645589"] There is also a much faster way to do this: Measure (Theoretical value) the angle of the slope to the horizontal, mass of cart, the time it takes to travel the length of the ramp. Calculate (Theoretical Value): The final velocity (v) of the cart, using suvat equations (u=0, time [measured], acceleration [calculated]). Acceleration is calculated from the Force parallel to the surface using the mass [measured] and angle of the ramp [measured]. Measure (Experimental value): Velocity at end of the ramp Therefore the acceleration would be equal to gravity multiplied by sin(of the angle of the ramp) and the final velocity would be calculated wither by v=u+at v^2=u^2+2as where t is time and s is displacement and a is the acceleration which was previously found. Also in orer to find the final velocity of the plack you can take a video of it going down the ramp and then analyze it through any of the video analysis programs in order to find the final velocity (tracker) is a free and easy to use option.
