The potential ene

Answer :

Given:

Potential energy (P.E.) =


Let,


X component of force = FX


Y component of force = FY






Let, net force




If, θ = angle that makes with the horizontal


Then,



Displacement of the particle is along a straight line path having, slope


Let, the equation of straight line be


Where,


m = slope


c = intercept


So,



This line passes through (6, 4)


So,





If the path passes through y-axis at (0, y0)


Then,


So the path crosses y-axis at (0, –4)


Displacement between (6, 4) and (0, –4) = s





u = 0


a = 5 ms–2


s = 10 m





The speed at which particle crosses x is =
