A small object with mass m = 0.0900 kg moves along the +x-axis. The only force on the object is a conservative force that has the potential-energy function U(x)=−αx2+βx3, where α= 7.50 J/m2 and β = 0.300 J/m3. The object is released from rest at small x. When the object is at x = 4.00 m, what are its
(a) speed and
(b) acceleration (magnitude and direction)?
(c) What is the maximum value of x reached by the object during its motion?

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.
