A ball moves in the x direction where x represents the balls position. The potential energy U of the ball in Joules is given as a function U(x)=6x^2-5x+4. The force on the particle at x=2m is:

Sorry my friend i don't know the answer. i am just in 6th

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

That would be kinetic energy
