S. A cart attached to a spring is displaced from equilibrium and then released. There is no friction. A graph of displacement as a
function of time for the cart is shown. The arrows and signs above the cart indicate the positive and negative directions for the
position of the cart.
(a) At which point or points is the acceleration positive?
(b) At which point or points does the cart have zero velocity but
nonzero net force?
A Displacement, cm
(c) At which point or points is the net force on the cart equal to zero?
A
16
Time
(d) At which point or points are the acceleration, velocity, and
displacement all positive? _
(e) At which point or points is the acceleration nonzero and opposite in sign to the position?
(f) At which point or points is the velocity nonzero and opposite in sign to the acceleration?
(b) At which point or points is the kinetic energy equal to zero?

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12×10−6 k−1 and23×10−6 k−1 respectively.

Suppose that a cylindrical tank 6 meters high with a radius of 2 meters is filled to the rim with water. the tank is buried so that the top of the tank is 1 meter below ground level. the space above the tank is not filled with water. calculate how much work needs to be done by a pump to pump the water out of the tank up to ground level. (the water weighs 9,800 newtons per cubic meter.)
