Question

A particle is released from rest at x =
1m. It moves under influence of a force
whose potential energy function is U =
x2 - 6x. Which of the statements are
correct?​

Answer 1

Answer:

$F=ma=- \frac{dU}{dx}\\\\\\ {mv}\frac{dv}{dx} =-2x+3\\\\on\; integration\\\\\\{m}\frac{v^{2} }{2} =-x^{2} +3x\\\\KE=3*2-2^{2} =2J$
