As the pendulum swings from position A to position B, what is the relationship of kinetic energy to potential energy (neglect friction)? (5 points) The kinetic energy increase is equal to the potential energy decrease.The potential energy increase is equal to the kinetic energy decrease.The kinetic energy and potential energy remain the same.The kinetic energy increase is more than the potential energy decrease.

A cat runs along a straight line (the x-axis) from point A to point B to point C, as shown in the figure. The distance between points A and C is 5. 00 m, the distance between points B and C is 10. 0 m, and the positive direction of the x-axis points to the right. The time to run from A to B is 20. 0 s, and the time from B to C is 8. 00 s. As the cat runs along the x-axis between points A and C what is its average speed?

Consider a ring, sphere and Solidey clinder all with the same mass. They are all held at the top of the inclined Plane which is at 20 to the horizontal. the top of the inclined Plane is Im high. The shapes are released simultaneously and allowed to roll down the inclined plane. Assume the abjects roll with out slipping and that they are all made from the same material. Assume the coefficient of static friction bin the objects and the plane is 0-3-a) worklout what orderthey would get to the bottom of the slope.b) How long will it take each shape to reach the bottom of the Slope ?c) which shapes have the greater moment of inertia ?d) determine the linear acceleration(a) e) calculate the tangential (linear) Veloci ty of each shapes-

A small object of mass m is shot horizontally from a spring launcher that is attached to a table. All frictional forces are considered to be negligible. The ball strikes the ground a distance d from the base of the table, as shown in the figure. A second object of mass m2 is launched from the same launcher such that the spring is compressed the same distance as in the original scenario. The distance from the base of the table that the object lands is.
